School of Medicine and Population Health

Research Interests

My research is focused on advanced breast and prostate cancer with particular emphasis on bone metastases. Primarily, this involves using a complement of in vitro and in vivo model systems to investigate the molecular alterations responsible for metastases to bone and response to treatment. Metastases are a result of a stepwise accumulation of genetic/epi-genetic mutations promoting distinct molecular alterations that drive different stages in the metastatic process; mutations involved in intravasation are not the same as those involved in tissue homing and colonisation. Importantly, molecular alterations acquired by tumour cells have profound effects on cytokine production and immune cell regulation. My research team hypothesise that cytokine driven changes to the tumour immune environment promotes metastatic spread and that pharmacological regulation of immunity may provide effective treatment methods for, currently incurable, bone metastasis. The aims of my research are to: (A) Identify specific molecular and immune cell regulatory determinants involved in tumour cell intravasation, homing to bone and colonisation of the metastatic site. (B) Decipher how these determinants impact on treatment efficacy in different cancer subtypes. (C) Establish more effective treatments for metastatic breast and prostate cancers.

Sheffield University Management School

Lecturer in Employment Relations

Edward Yates is a Lecturer in Employment Relations in the School of Management at the University of Sheffield.

Edward is a member of the Centre for Decent Work (CDW) located within the Management School.

Edward’s research explores the relationship between processes of political economy, state regulation, employment relations and labour market outcomes. He is particularly interested in the behaviour of local labour markets, in particular for young workers. Edward’s current research is organised into four main areas:

  1. Local labour markets. Specifically how processes of capitalist accumulation manifest in and through local labour markets and how this is expressed in the behaviour of local state actors, local employers, and workers.
  2. State regulation of work, employment, and labour markets. In particular how shifts in the global economy in the last 50 years have impacted upon state policy for labour market regulation and what this means for workers.
  3. Young workers. Edward’s research examines central and local government policy regarding young workers, wage-rates for young workers, conditions of work and employment, skills and training provision, and the theoretical development of a ‘political economy of youth’.
  4. Work, employment and labour markets in the NHS. This strand of research explores contemporary conditions of work and employment in the NHS for different staff groups and occupations.
    • The research examines: the intensification of working conditions in the NHS, processes of churn and attrition, pension changes, the role of trade unions and professional organisations in the NHS, and NHS financing.

In addition to these four research areas Edward is interested in the theoretical development of critical, global political economy, and in research methodologies.

Research interests

We are particularly interested in bacterial colonisation of the host, in relation to how bacteria perceive surfaces and their subsequent interactions. This had led to the research directions of investigating surface (swarming) motility and glycosylation of the bacterial flagellum with unusual sugars that can be potential targets for anti-microbial therapy.

Use of Aeromonas species as model systems for bacterial colonisation, environmental adaptation and protein glycosylation

Aeromonas spp. are an increasingly important cause of gastro-enteritis, with A. caviae being important in the causation of paediatric diarrhoea. However, there is little known about the pathogenicity determinants of this organism. Some strains of Aeromonas express two distinct flagella systems, a polar flagellum for swimming in liquid environments and many lateral flagella for swarming over surfaces, both are involved in colonisation. Possession of two types of flagella provides a natural reporter system for investigating how bacteria sense surfaces, or for dissecting the bacterial sense of touch. We are also interested in the genetic cross-talk between the flagellar systems and the type 3 secretion systems (T3SS).

Aeromonas glycosylates its flagellum with the sugar pseudaminic acid, this is essential for flagellar filament assembly and motility. This sugar is also found on the flagellin proteins of Campylobacter jejuni and Helicobacter pylori. We are elucidating the flagellar glycosylation process at the molecular level. We are interested in developing sugar analogues to inhibit the glycosylation process that could possibly be used as a novel form of anti-microbial therapy.

Studies into the virulence and physiology of  the pathogenic Neisseria

Neisseria meningitidis is a major cause of bacterial meningitis. Although quite a lot is known about the organism's virulence factors, there is very little information available about the organism's carbon metabolism. We are investigating the growth and metabolic characteristics of N. meningitidis through the use of 13C-NMR and enzyme assays, with the emphasis on growth on lactate. This will enable us to find out what metabolic pathways the organism uses in CSF (in vivo) and find out if any unique enzymes are present which can be rationally targeted for antimicrobial therapy. The role of these pathways in the organisms pathogenesis are also being considered. We are also investigating the role of the global regulator Lrp (leucine responsive regulatory protein) and the stringent response of N. meningitidis in pathogenesis.

How do cells integrate information to make decisions about what genes should be expressed at a given time and in a given place? How do these processes malfunction to produce disease states? The correct regulation of gene expression is essential for the proper functioning of the cell, and incorrect regulation of genes is central to the mechanisms of many diseases. My interests rest in understanding how the many levels of eukaryotic gene regulation work together to perform these functions, using computational and functional genomics tools.

The role of microRNAs in regulatory networks


microRNAs (miRNAs) are short, single stranded RNAs that act to down regulate the expression of their targets by transcript destabilisation and translational inhibition. What roles to these molecules play in the information processing systems of the cell? How might these roles differ from that provided by transcriptional inhibitors? We know that miRNAs are found enriched in different topologies of network motifs than transcription factors. What might explain this?

Mathematical modelling suggests that miRNAs might threshold the expression of their target genes, only allowing protein production once transcription exceeds a particular rate. However, thus far experimental tests of this model are lacking in realistic in vivo settings. We are studying evidence that might speak to the applicability of this model in real biology, and studying the consequences of this behaviour on regulatory networks and the identification of miRNA targets.

Misregulation of chromatin structure in disease


A cell’s DNA does not exist as a single extended string of nucleic acids in the way often imagined, but rather is packed and folded in a myriad of ways to form a complex three dimensional structure. At least some of this structure is thought to be important for the regulation of gene expression. Transcription of metazoan genes is regulated by sequences known as enhancers which integrate diverse signals to make decisions about expression, and then communicate these decisions through their interactions with promoters. This communication is thought to take place via physical interactions between promoters and enhancers.

Together with collaborators from the Imperial University we are investigating how this three dimensional structure might contribute to the miss-regulation of gene expression in both monogenic disease and cancer using high-throughput, next-generation sequencing based assays of chromatin conformation.

Sheffield University Management School

Senior Lecturer in Employment Relations

Jo has published work and research interests fall broadly into the following categories:

  • Decent Work in Decent Workplaces
  • Job Quality
  • Regulation of Work and Employment
  • Labour Movements, Voice and Vulnerability
  • Global Value Chains, Labour and Labour Process Theory

It does so by firmly placing the political economy of industrial relations and the labour process, within its broader capitalist context.

Given this overarching focus, Jo's work examines (both empirically and theoretically) the power asymmetry that underpins the employment relationship, and the contrasting and conflicting priorities and interests.

Specifically it examines the political economy and public policy associated with employment relations (particularly with regards inequality, both in terms of pensions, pay and conditions), and how labour market reform shapes the experience of work for so many; how labour market regulation facilitates this; how this then is transmitted globally via financialized capitalism; and finally the dynamics of collective resistance to these issues by trade unions and workers.

In addition, her research analyses the ways in which financialization of the employment relationship plays out at macro, meso, and micro levels.

Rather than simply theorising financialization – as so many other have done – Jo's research examines and analyses how precariousness (which is institutionalised by legislation) makes citizens more amenable to low pay via activation labour market policies and labour market deregulation more generally.

It also examines how regulation (informed by neoliberal ideology) has helped produce an environment where organisations appropriate value from their staff as a contemporary strategy, particularly via company pension schemes.

Underpinning these research interests is a focus on developing an empirically informed, theoretical model of how ‘financialized capitalism’ appropriates shareholder value from employees, and the role that regulation plays in facilitating this.

To date this has included, re-examining the pension crisis in the UK. But also, connecting this more broadly to the development of ‘financialized capitalism’ and the pursuit of shareholder value.

I am a social psychologist, interested in self-regulation and behaviour change. Specifically, I am interested in how people achieve their goals and make changes to their behaviour.

The usual answer is that people need to be motivated. However, even medium-to-large changes in people's intentions seem to have only a small-to-medium effect on their behavior. In short, motivation is not enough. As a result, much of my research to date has investigated how the effects of motivation can be boosted by forming specific plans - known as "implementation intentions" - that links good opportunities to act with suitable responses to those opportunities.

My long-standing research interests have been focused on the role and regulation of epithelial secretory proteins. This work has principally involved the study of the airway epithelium, through the use of 3D in vitro model systems, but more recently has expanded to include the oral and nasal mucosa and the epithelium of the middle ear. My specific interests have focused on the fields of innate immunity, host defence and tumour biology.

I have also recently started to investigate the potential of using my tissue culture expertise to develop in vitro models of human salivary glands from fresh human tissue. We are now routinely isolating cells from human sublingual glands and are currently characterising cell phenotype under different culture conditions. The mid-term aim is to use these models to begin to elucidate the initial stages of salivary gland diseases such as Sjogren’s syndrome and salivary gland tumours.

My current research is focused on the regulation of follicle development in the mammalian ovary. In particular, I am interested in the early, gonadotrophin-independent stages and how various signalling pathways are used to establish gradients and communication networks in a three-dimensional context. 

The aim of these projects is to understand how the ovary, with its limited supply of oocytes, is able to selectively encourage some follicles to develop in a timely manner, while others remain in a relatively quiescent state. We use molecular tools and 3D imaging to investigate these processes in ex vivo cultures and draw novel insight from mathematical models. Part of this research is being investigated within the clinical context of disorders of follicle development such as Premature Ovarian Failure and Polycystic Ovary Syndrome.

My research interests to-date center on urban climate governance. I am especially interested in the politics of urban adaptation and resilience planning and the ways in which cities come to "know" and act on climate risks. Thus far, I have conducted research on these subjects in Miami, New York, New Orleans, and the Bay Area. I take a highly interdisciplinary approach to my work, and regularly engage with debates in urban and economic geography, political ecology, science and technology studies, and urban planning.

My research has focused on issues such as: how key players within global financial systems are developing their understandings of urban climate vulnerability and resilience and the implications for climate-changing cities; how resilience efforts intervene in, and stand to reconfigure, longstanding racial formations in cities; how climate justice activists mobilize resilience to make claims to the city and its future, as well the significance of the resilience and design turn within the field of urban planning more broadly.

Matthias’s research has focused on contemporary Sociological Theory and Social Science Methodology. His work explores the potential contributions of Critical and Poststructuralist Social Theory to the sociological study of contemporary capitalist society: of its dominant social relations and of their implications for human life and thought. Moreover, Matthias has examined the methodological challenges of 20th and 21st century Social Theory to Sociology’s epistemological, empirical and methodical, interpretive and analytical, socio-critical and normative, and textual dimensions.

Matthias’s current research project centres on a sociological inquiry into the operations of quality of life ideas in the health sector, notably in healthcare regulation. His analyses focus on: definitions of quality of life; measurement and valuation instruments; operationalisations of quality of life conceptions in regulatory work, especially in cost-effectiveness analysis; and connections between quality of life ideas and approaches to human suffering and death. Operations of quality of life ideas are investigated in view of their underlying knowledge base, their implicit normative commitments and value judgements, their governing bioethical principles, and their political orientations. The project addresses discussions on capitalism’s dominant modes of valuing human life and of conceptualising happiness and the good life as well as damaged and bad life, responses to human suffering, and approaches to finitude, dying, and death. The project seeks to intervene in the sociological debate on prevalent biopolitical configurations with a view to the conceptions of, and interventions in, individual and population life they entail.

  • Sociological Methodology
  • Cultural Theory
  • Quality of Life Debates
  • Biopolitics

He is also interested in supervising theoretically informed empirical sociological research on health and illness, healthcare, suffering, and death.

Matthias has supported doctoral students working on topics such as the social dimensions of MP3s, media constructions of social class, racism in language education, hospices, deinstitutionalisation, and the fitness industry.

My doctoral research developed a method of combining (Faircloughian) critical discourse analysis with corpus linguistic tools in the analysis of education policy. I drew also on regulation school state theory in order to critically examine the evolving relationship between policy agendas and wider developments in the UK economy, politics and society. I am particularly interested in the way policy discourse is used to construct and legitimate neoliberal identities, roles and power relations between citizen and state. Key themes explored in my recent publications are the historic emergence of an ‘enabler’ model of governance and the use of ‘personalisation’ as a legitimation strategy in policy.

More generally I am interested in the strategic role of (national) policy discourse in recontextualising, disseminating and legitimating dominant political imaginaries in advanced liberal economies. My current research applies and elaborates this approach to critically explore the social construction of ageing in the UK. Focussing on policy and public discourse, this work aims to contribute a critical discourse perspective to academic debates on societal and political responses to population ageing.

Aberrant secretion of neurotransmitters, hormones or immune mediators contributes to the pathology of a wide variety of chronic neurological, endocrine and inflammatory diseases ranging from stress and hypertension through to asthma and irritable bowel syndrome. Research in our lab is focussed on identifying the signalling pathways and molecules controlling secretion from neurones and mast cells, with a special interest in voltage-gated (CaV), ligand-gated (P2X and nAChR), receptor-operated (TRPC) and store-operated (Orai) calcium channels, IgE and G protein coupled receptors (P2Y, Histamine), and SNARE regulatory proteins (synaptotagmins, Doc2 and Munc13).  Most of our work is performed at the level of isolated primary cells using high resolution techniques including patch-clamp electrophysiology, carbon fibre amperometry, calcium imaging and total internal reflection fluorescence microscopy with various fluorescence-based biosensors.

Recent highlights of our research include (1) the discovery of ATP-sensitive P2X receptors on human lung mast cells, activation of which may contribute to the pathophysiology of asthma, (2) the first demonstration of Munc13 as an essential effector of phospholipase C-coupled G protein coupled receptor regulation of neurotransmitter release in mammalian  cells, and (3) the modulatory action of synaptotagmin IV on the calcium-sensitivity of the neuronal fusion machinery.

My research focus is on the regulation of angiogenesis, the development of new blood vessels from the pre-existing vasculature, in wound healing and tumour development and progression. Angiogenesis and haemostasis, the coagulation cascade leading to clot formation, are among the most consistent host responses associated with cancer. Many haemostatic proteins stimulate angiogenesis by up-regulating the expression of vascular endothelial growth factor (VEGF) and its receptors on endothelial cells. Other haemostatic proteins act directly on endothelial cells to inhibit or stimulate angiogenesis. Moreover, recently proteins originally identified as important in neuronal guidance are now suspected to be involved in regulating angiogenesis, both positively and negatively. Thus a comprehensive understanding of the relationships between these important processes under normal conditions (such as wound healing) and in the manner in which this changes during development and progression of cancer has implications for cancer therapy. Collaborative research with colleagues in Sheffield also includes investigating the effects of HDACi on the expression of these and other angiogenesis related proteins in cancer, and the potential anti-angiogenic effects of the ADAMTS family.

My long-standing research interests have been focused on cellular differentiation and regulation of gene expression within the developing and adult pulmonary epithelium. This work involves the isolation of pulmonary epithelial cell specific genes (principally the BPIF/PLUNC and WFDC families) as well as the transcription factors, which regulate their expression. This work also involves studies of epithelial cell specific differentiation and understanding the role of distinct stem/basal cells in this process. This work has allowed me to use disease models, human clinical material and our novel genes to study aspects of pulmonary cell plasticity in the lung and changes that occur in IPF and COPD

Over the past few years my interests have also expanded into the fields of the genetics of complex diseases, pulmonary immunology, innate immunity and host defence and now a major focus of my work is on pulmonary innate immunity, the control of pulmonary inflammation and the role of innate defence pathways in the development of chronic lung disease.

I also work extensively with primary human and mouse airway epithelial cells in differentiated air liquid interface cultures using them as tools to understand the regulation of airway epithelial cell specific genes. At a more clinical level we are also studying host/pathogen interactions using both viral (RSV, flu, MHV68) and bacterial (Pseudomonas, Staph, NTHi) infections. This work has allowed me to align myself with the work of the Florey Institute for Host/Pathogen Interactions. In addition to our airway studies we have also developed primary middle ear epithelial cell cultures for our work on infections in Otitis Media which complements my developing interest in middle ear biology.

This applied work has allowed me to continue to study the role of epithelial differentiation in the airways and to use disease models and our novel genes to study aspects of pulmonary cell plasticity in the lung. This is particular focused on epithelial changes in the lungs of patients with IPF and COPD. Our recent work has begun to uncover a role for BPIF proteins in the pathogenesis  of lung disease using both human material and murine models. It has also led to new avenues of work that focus on the epithelial responses in nasopharyngeal infections and in Otitis Media.

Diego's research interests are mainly focused on the wide area of facility location and related problems. He has particular interest in network restructuring, facility delocation (closing), and applications of facility location models and techniques to problems that are not necessarily locational.

Diego is also interested in the problem of proliferation in the market place. This problem (associated with the existence of numerous products, markets and channels) is a consequence of the quest for growth in highly competitive and slow growing markets, and introduces severe and costly complexities in the firms organisation's fabric, and has important effects in the its operations and its supply chain, while simultaneously raises important sustainability concerns. Diego and his co-authors have proposed an entropy-based measure for complexity and have established its empirical relevance and practical relevance in collaborations with renowned forms of global presence. Their work is now is heading towards the identification of mechanisms for controlling complexity and lessening its impact on the firm's finances.

Finally, Diego continues his previous work on stochastic scheduling and dynamic resource allocation. He is currently working on the problem of scheduling preventative maintenance interventions for systems consisting in a large number of independently deteriorating equipment. he has special interest on applications to off-shore wind farms.

Students interested in further exploring the problem of complexity in the supply chain, and its implications on resilience and sustainability, are encouraged to send their proposals. Diego is also keen on working with students with interests in facility location, distribution, routing, scheduling, and other problems in supply chain and operations management, as well as more generic problems in management science.

I have interests and expertise in self-regulation – how people direct their thoughts, feelings, and behaviours in order to achieve their goals – and in the design, application, and evaluation of interventions designed to promote positive and lasting changes in people’s behaviour. My research uses theoretical models of behaviour (e.g., control theory, COM-B model, theory of planned behaviour) in order to understand why people’s efforts to self-regulate are sometimes compromised and how this process can be promoted. I collaborate with a range of stakeholders in order to understand behaviour in different contexts and I am passionate about collaborating on interdisciplinary research projects, where global challenges are considered from multiple perspectives and solutions are informed by a wide range of expertise.

I am currently involved in three lines of research:

• I am working with scientists across the university on a project that seeks to reduce the impact that plastic waste is having on the environment. My research seeks to understand people’s attitudes and behaviours towards plastic, and we are testing strategies and interventions designed to promote the use of reusable packaging and containers. I am also collaborating with colleagues from the School of Dentistry exploring the publics’ attitudes towards sustainability in healthcare, and their willingness to make sacrifices for more sustainable healthcare services.

• I am working with psychologists and computer scientists to develop a set of tools to allow people (e.g., academics, practitioners) to explore the relationship between different behaviours. While the relationship between some behaviours may be intuitive (e.g., the relationship between different health behaviours), others may be less intuitive (e.g., whether health behaviours are associated with pro-environmental behaviours). Such tools will allow users to test a wide range of hypotheses about how (and when) different behaviours are related.

• I am interested in how individual differences (e.g., in people’s time perspective) influence people’s behaviour and goal outcomes.

I’m interested in the development of children’s executive functions, which are the collection of cognitive skills that support goal directed thinking and self-regulation. I am interested in how they develop in toddlers and preschoolers, why we see individual differences in these skills and how their development can be best supported. My research also examines how executive functions might relate to school readiness and how social inequalities might shape their development.

I am currently leading an ESRC funded longitudinal study 'The Sheffield Early Years Study' to examine how executive functions develop in the toddler and preschool years. I am interested in the important role that parents play in buffering the impacts of social inequality and how language may shape the development of executive functions. For more information, please see our project website here.

I am currently working with colleagues at the University of Oxford and Ulster University to design and evaluate interventions to support maths skills and cognitive development. In one study we are trialling whether we can reduce socioeconomic disadvantage in early maths by working with practitioners to embed executive functions into fun learning activities (The ONE intervention; funded by the Education Endowment Foundation). In another study, we are examining the role the home environment plays in early maths by running secondary analyses on a large-scale dataset and designing and trialling a co-produced parent intervention (PLUS study; funded by the Nuffield Foundation).

I'm also leading a research project with Fiona Scott in the School of Education, Michelle McGillion (University of Warwick) and the National Childbirth Trust to understand the unique experiences new parents have faced during the COVID-19 pandemic. Please see the project website here.

In particular, we are interested in understanding the interplay of cell growth and division and how these parameters are integrated into the developmental program controlling leaf size and shape. Using techniques of cell and molecular biology, we are testing hypotheses on the regulation of organogenesis. At the same time, these approaches provide functional data on gene products implicated in basic aspects of the plant cell cycle and the plant cell wall. Our focus is on an integrative approach in which, in addition to cell and molecular techniques, we are incorporating computational modeling, physiology and biochemistry to provide an organismal-level understanding of leaf formation and function.

In addition, as a result of our interest in cell division and the cell wall and how they are integrated into plant function, we have become involved in a range of collaborative ventures. For example, the interplay between development, physiology and metabolism has led to novel joint projects aimed at developing/implementing techniques for the visualization and analysis of metabolites at the cellular level and their integration with developmental processes (Paul Quick, Mike Burrell). The cell wall also plays an important role in the functioning of specific cell types required for leaf function and this has led to joint EvoDevo projects looking at aspects of plant evolution (David Beerling, Julie Gray, Charles Wellman).

The group has a strong tradition of pan-European research. If you are interested in applying for a EU-Marie Curie Fellowship to work with us, don´t hesitate to make contact.

Tissue Repair and Immunity in Ageing (TRIA)

Why we age and whether we can therapeutically prevent associated diseases has been my continued research motivation. And this is because age is the greatest risk factor for chronic diseases such as cancer, frailty, muscle atrophy, arthritis and many others. This means we are living longer than ever before, but with a heavy burden of disease which impacts on our quality of life and poses serious socio-economical challenges we must meet.
Ageing is underlined by a progressive decline in tissues ability to repair and maintain themselves. This is what is called tissue homeostasis impairment and sets the ground for age-associated diseases. A key mechanism contributing to this is telomere shortening and dysfunction. In organisms with restricted telomerase activity, which is the case of humans and zebrafish, telomeres shorten and get damaged with ageing, causing cells to die or become senescent. Senescent cells no longer divide and secrete factors that somehow impair the repair capacity of our tissues and organs, thereby contributing to disease.

Tissue homeostasis requires a tight balance between the clearance of senescent and damaged cells by the immune system and the replenishing of new cells from the stem cell niche.

My research programme focuses on understanding the interplay between immune regulation and tissue homeostasis in health and with ageing, using zebrafish as a model. My ultimate aim is to identify therapeutic targets that can be used to incentivate tissue rejuvenation and ameliorate multiple co-morbidities of ageing

Research Interests

I have two established streams of research. Both streams aim to further our knowledge of socially responsible and sustainable practices. One focuses on individual level practices and the other focuses on organisations and industry.

At the individual level, I focus my research on building our understanding of how individuals’ roles and experiences outside of work influence their work lives, and vice versa. To do this I examine the impacts of leisure activities, idiosyncratic deals (‘i-deals’) and interpersonal emotion regulation on employees work and non-work lives. My research contributes to the literature on work-life enrichment by providing a more nuanced understanding of the roles individuals fulfil, beyond the traditional focus on family. It sheds light on broader mechanisms that facilitate individual success and productivity in the workplace. I do this through intensive longitudinal quantitative methods- often referred to as diary studies.

At the organisational and industry level, my research deals with how businesses and public bodies can positively impact wider society.

I have worked on multidisciplinary projects such as:

  • Comparative Police Studies in the EU (COMPOSITE), a European project examining policing processes across countries.
  • Mainstreaming Assisted Living Technology (MALT), a TSB funded project aiming to facilitate the large scale introduction of telehealth technology.
  • Active Workforce Initiative (AWI), a BOHRF funded project examining the impact of positive psychology interventions on the well-being of police and health workers.
  • Business Driven Social Change, an NBS funded review of literature on the techniques and outcomes of business driven social change.

PhD Supervision

I am interested in supervising PhD students who would like to examine issues to do with the interface between work and other life domains - this can include work-life balance, enrichment and conflict pertaining to family and leisure domains as well as the impact of supportive supervisor behaviours on work-life balance.

Our research group is focussed on understanding how cells divide in normal tissues and during cancer development and metastasis. To do this we take a multidisciplinary approach, combining imaging and cell biology with biophysical techniques to measure mechanical forces associated with cell division.

Cell shape and mechanics during cell division

Cells go through a series of dynamic shape changes when they divide. These include cell rounding and stiffening in early mitosis and separation into two daughter cells at cytokinesis. We want to understand how these changes are co-ordinated by dynamic regulation of the actin cytoskeleton throughout cell division. We are particularly interested in how cells divide within epithelial tissues where they must maintain attachment with neighbouring cells to preserve tissue integrity and organisation.

Cell division in cancer

Cancer is a disease of uncontrolled cell proliferation and division. We are investigating how genetic mutations in cancer cells affect the cell division process. In recent work, we found that Ras oncogenes change cell shape and mechanics during mitosis (Matthews et al. 2020). We are now exploring how changes to cell division induced by the oncogenic kRas promote the formation of tumours during the early stages of pancreatic cancer development.

We are also interested in how the modified micro-environment within a tumour affects cancer cell division. Tumours are usually far stiffer than healthy tissue due to cell crowding and the deposition of extra-cellular matrix. We use micro-fabrication techniques to mimic some of the mechanical stresses (eg. compression, stretch) found in tumours to study how these conditions impact cell division.

Research

Kirsty’s research interests are focussed around three interconnected core themes: the changing character of employment regulation; the shifts and transformations in the politics of production; and the dynamic interplay of global value chains and the labour process. In recent years the empirical focus of her research has been two-fold. First with Professor Paul Thompson and Johanna Commander (University of Strathclyde), she has been concerned with exploring labour process change in the supermarket supply chain. Second, funded in part by a grant from the Nuffield Foundation, Kirsty has focussed on examining the interplay of internal and external forces in the restructuring of the employment relationship, the labour process and value chains in retail distribution and logistics. She is currently co-editing a book entitled ‘Putting Labour in its Place’: Labour Process Analysis and Global Value Chains with Professor Phil Taylor, Dr. Jennifer Bair and Professor Al Rainnie published by Palgrave Macmillan. Kirsty’s current research focus is to explore changing work and employment within the logistics sector.

Kirsty is a member of the team (with Professor Paul Stewart, Professor Dora Scholarios and Ms Claire Scott, University of Strathclyde) which co-ordinates the research network "The changing nature of employment in Europe in the context of challenges, threats and opportunities for employees and employers". This is an international comparative European FP7 Marie Curie Initial Training Network (ITN) of Early Stage Researchers (ESRs) and Experienced Researchers (ERs). It is amongst a small number of multi-disciplinary social science programmes to be awarded funding in the current Marie Curie awards under the European Union’s Seventh Framework Programme for Research and Development (FP7). The ITN, brings together new and recent post graduate researchers working on an international post graduate research programme supervised by internationally renowned senior academics.

The focus of both my clinical and basic research is on optimising pituitary hormone replacement. My group have identified and characterised uncommon mutations in the growth hormone receptor which have led to fundamental observations on the mechanism by which the growth hormone receptor signals through a pre-formed dimer. This work has led to a greater understanding of the regulation of growth hormone secretion and recently the group have developed a long acting form of growth hormone which has exceptional pharmacokinetic properties that means administration may only be required once a fortnight or once a month. This work was published in Nature Medicine in 2007.

The Clinical Research Programme has been investigating different regimens for replacing cortisol, testosterone and oestrogen in hypopituitary, hypogonadal and adrenal insufficient patients. The group have designed a new modified release form of hydrocortisone, Chronocort, which in phase 1 studies has proven to replicate the normal circadian rhythm of cortisol. This work is currently being taken through to phase 2 studies in congenital adrenal hyperplasia patients. Other work has examined the incidence of hypogonadism in cancer survivors and optimising oestrogen replacement in young women of fertile years.

I co-chair the Endocrine Unit Management Team which consists of 6 Consultant Endocrinologists and runs a number of unique and innovative specialist clinics in the Health Care Trust including: Pituitary Clinic, Transition Clinic for Paediatric Endocrinology, Late Effects Clinic for Cancer survivors, Joint Surgical Endocrine Clinics, Obesity Clinic, Genetic Endocrine Clinic and a Pituitary Multidisciplinary Team.

Work in my lab focuses on molecular mechanisms governing bacterial cell growth and division within the host environment. We study the ellipsoid-shaped model organism and human pathogen Streptococcus pneumoniae.

Pneumonia and meningitis are leading causes of death in the world. These diseases are caused by a variety of bacteria but are commonly caused by invasive S. pneumoniae. How these bacteria grow and divide inside their hosts is fundamental to our understanding of these conditions. My lab focuses on S. pneumoniae growth and division processes. Specifically, how the process of cell wall biosynthesis is governed and coordinated to maintain the cell shape and integrity as the cells grow and divide.

As S. pneumoniae cell growth takes place exclusively within the human host, we study the cell host-cell interactions to provide context of cell growth processes. We study how S. pneumoniae cells adapt to environmental changes within hosts, resist clearance by the immune system and cope with antibiotic challenges.

We use genetic screens, biochemical assays and epifluorescence microscopy to advance our understanding of the molecular mechanisms behind these processes.

Identification of a new cell wall biogenesis factor CozE using Tn-seq

Our recent work has utilised a genetic screening technique called Tn-seq 1-3 to identify a new cell wall assembly factor: CozE. Broadly, the Tn-seq technique starts out with large populations of bacteria, each containing an individual gene inactivation. A selective pressure is applied to this population killing some of the more sensitised members. Next, all surviving members are sequenced and their individual gene inactivation is identified (Figure 1A). In this study, we exploited a known genetic relationship between two cell wall biosynthetic factors, PBP1a and PBP2a, to screen for new genes involved in the regulation of these enzymes. Examples of Tn-seq insertion profiles generated from this work are shown in Figure 1B. These insertion profiles revealed a novel cell wall biogenesis regulator in bacteria, which we named CozE for Coordinator Of Zonal Elongation.

 

CozE is essential for coordinated cell wall synthesis

Most bacterial cells are surrounded by a cellular exoskeleton called the cell wall. This structure gives the cells their shape and protects them from osmotic lysis. Our Tn-seq study identified the membrane protein CozE, which is essential for coordinated cell wall synthesis in S. pneumoniae (Figure 2A). The cell wall of S. pneumoniae is synthesised in a highly regulated manner involving the action of many enzymes. Removing CozE from S. pneumoniae cells effectively shatters this machinery into its composite pieces, dispersing them throughout the cell surface. Surprisingly, the PBP1a component of the machine appears to keep on working. Like an assembly line out of control, PBP1a synthesises new cell wall seemingly all over the place, inserting new material in inappropriate places. The cells are unable to cope with the aberrant synthesis, which makes them swell and eventually lyse (Figure 2B). Our current work focuses on understanding this rogue cell wall synthesis activity further to see if we can ultimately exploit it for future therapies.

For more information on CozE, please read our paper CozE is a member of the MreCD complex that directs cell elongation in Streptococcus pneumoniae.

The World after Empire: themes include Muslim geographies and postcolonial cities 
Two generations after it was broken up, the British Empire lives on in a number of ways, including through communities that trace their heritage and origins to former colonies, and in cities, born of empire, that are forced to redefine themselves for new times. I have investigated these issues through research involving British Muslims and members of the Liverpool-born black community (see Muslim Spaces of Hope, published in 2009, and Liverpool ’81: Remembering the Riots2011). I have also researched the ways in which empire is invoked in contemporary political action, through a project on anti-imperialism in the UK anti-war movements (which protested intervention in Afghanistan and Iraq). I have also investigated the historical geographies of the British Empire through studies of colonial travel and adventure literature (Mapping Men and Empire: A Geography of Adventure, 1997) and through an historical geography of sexuality politics in the British Empire (Sex, Politics and Empire: A Postcolonial Geography, 2006).

Sexuality, Space and Power: constructions and contestations of sexual identities 
Sexuality is an important vehicle for constructing and contesting power relations between national, cultural and religious groups. I have traced imperial sexuality politics through key sites within the British Empire, investigating the legacies of these colonial histories and geographies in ex-colonies including Jamaica and Sierra Leone. I have also begun to examine these dynamics within Europe, investigating cultural practices through which Muslims are constructed as 'non-liberal' minorities, through representations of forced marriage and homophobia. My books about sexuality investigate the contested regulation of sexuality in the British Empire (Sex, Politics and Empire: A Postcolonial Geography, 2006), examine sexuality politics and identities outside the cities that dominate research on sexualities (De-Centring Sexualities, 2001), and investigate the place of sexuality within sometimes tense relationships between majority societies and cultural minorities (controversies surrounding Muslim attitudes towards marriage and homosexuality are examined in a paper published in Gender, Place and Culture, 2012).

Curiosity and Adventure: from children’s books to health and wellbeing policies
My first book, entitled Mapping Men and Empire: A Geography of Adventure (1997), investigated boys' adventure stories, tracing their significance for constructions of imperialism and masculinity. I have subsequently researched and written about adventures through a range of juvenile and adult literature, notably travel writing. My more recent work focusses upon a term closely related to adventure – curiosity – through research on ‘space for curiosity’ (the title of a paper in Progress in Human Geography, 2014) and interventions on the sometimes celebrated, sometimes embattled place of curiosity in universities (paper in Transactions of the Institute of British Geographers, 2010). My interests in curiosity extend to a practical and philosophical approach to pedagogy, and a desire to better understand and encourage curiosity-driven learning among students was the motivation behind my book for students on the subject of geographical fieldwork: Fieldwork for Human Geography (2012).
