Four-year Wellcome Trust PhD studentships in Public Health, Economics and Decision Science

We seek to train the next generation of researchers in conducting high-quality research into the effectiveness and cost-effectiveness of complex multi-component public health interventions and policies to reduce non-communicable - or chronic diseases. Funding is available for four cohorts of five top-calibre PhD students to work on some of the most pressing public health challenges.

"This is unequivocally the best PhD program in health economics available in the United Kingdom, and potentially beyond. The independence you have as a researcher is unparalleled, and the research funding is second to none. If you want to do impactful research on the intersection between health economics, public health and decision science there is no better place to be than the wonderful (extremely green) city of Sheffield".

Why we have developed this programme

Helping to tackle major chronic diseases

Chronic disease accounts for the majority of the burden of disease in the developed world. Much of this burden is due to avoidable lifestyle behaviours – especially smoking, alcohol consumption, poor diet and physical inactivity. This burden can be reduced through well-targeted and coordinated public health policies.

Public Health Decision Science explicitly seeks to identify which combinations of interventions to prioritise for action and to estimate their return on investment.

In a health resource–constrained environment, there is an urgent need for a highly skilled workforce with expertise in decision modelling to support resource allocation decisions, by providing estimates of the long-term impact of public health interventions for different population subgroups, including detailed analysis of costs and benefits.

Decision-makers in the UK and internationally require evidence on (a) which combinations of interventions would most effectively reduce chronic disease burden; (b) what trade-offs exist between the outcomes prioritised by different stakeholders; and (c) which resource allocations will deliver greatest return on investment. Development and synthesis of new scientific evidence is crucial to answering these challenging questions.

Some of the main benefits of being on the WTDC programme are the number of researchers and professors working in related fields who are willing to help and often serve as an invaluable resource, and the high calibre of your peers who are also working in related areas and who come to the programme with different prior knowledge.

Rob Smith, Cohort 1

Novel multidisciplinary working 

Public Health Decision Science is an exciting cross-disciplinary area of research that draws on skills from across traditional departmental boundaries, including:

  • mathematics, statistics, economics, psychology, sociology, health economics, systems engineering, business studies, politics, and geography.

Our mission is to enable the highest calibre postgraduate researchers to build on their existing discipline-specific knowledge, and to complement this with training in another field.

To develop a true multidisciplinary cohort of scientists, we will support excellent health and related disciplines graduates in developing advanced quantitative analytical skills; and equip top mathematics, economics, systems engineering and related disciplines graduates with public health training and methodological expertise.

Individually tailored training

Our programme is structured to allow students to define their own learning trajectory, in discussion with their programme tutors.

The first year of the programme offers a unique training opportunity. Students attend a bespoke selection of 4 taught masters modules which complement their previous background and interests, engage in cohort-based research training activities, engage with senior scientists and meet public health leaders in monthly 'meet a decision maker' sessions.

Rotations through three 'research attachments' chosen from a list of options will allow students to develop experience of working in different topic areas and with different potential supervisors before making a final decision about the direction of their own PhD thesis work, and appropriate supervisory panel, in years two to four of the programme.

Researchers in ScHARR are keen to share ideas and support early career researchers. The programme offers unique opportunities for research and helps you to develop your career in a very supportive environment. I would recommend the programme to anyone who is interested in building a strong career that brings together Public Health and Health Economics.

Nicolas Silva, Cohort 2

Future careers in academia or decision making organisations

Our programme will prepare graduates to develop rewarding careers in academia or stakeholder organisations which will allow them to contribute to public health policy decisions to reduce the burden of disease in the UK and internationally.


We aim to:

  • Establish the world’s first Doctoral Training Centre in Public Health, Economics and Decision Science capitalising on existing infrastructure and research excellence
  • Make significant contributions to methodological development and scientific evidence on how to tackle chronic disease burden through well-evidenced, cost-effective public health strategies.
  • Create and sustain a cohort of multidisciplinary public health science leaders who develop excellent careers in academia and stakeholder organisations, fully engaged in public health policy making and reducing the burden of chronic disease in the UK and internationally.
Why Sheffield? ScHARR REF WT Image

ScHARR provides an excellent research environment

ScHARR is a multidisciplinary school with over 320 staff, including over 30 professors. It has an annual research grant income of over £10m and ranks 4th for research ‘power’ and 2nd for ‘impact’ in the UK league tables for its subject area (REF2014 UK UoA2).

ScHARR is fundamentally multidisciplinary. It spans applied and methodological, primary and secondary, qualitative and quantitative health related research with an explicit focus and mission to support UK and international decision making.

We are renowned for the quality of our research and our staff. We have expertise in public health policy appraisal, health economics, cost-effectiveness modelling, health services research, trial design, evaluation of complex interventions and valuation of health and well-being.

ScHARR consistently attracts high calibre individuals from a wide range of backgrounds including health, psychology, mathematics, statistics, the physical sciences, computer science, engineering and the quantitative social sciences, and pathways for moving between quantitative disciplines and health related research are well-trodden. As well as attracting grant funding, the School has a successful track record in winning studentships and fellowships that have facilitated training at doctoral and post-doctoral levels in economics, statistics and computer modelling. The School hosts a number of large programmes that add value to the doctoral training environment. ScHARR is a member of the NIHR School for Public Health Research and CLAHRC Yorkshire and Humber, and through these programmes fellows have access to a large network of researchers working on applied public health topics.

Postgraduate teaching and research is priority

There are currently 100 doctoral and 250 masters students in the School, providing a vibrant postgraduate environment. As part of the University of Sheffield, we have a well-developed approach to PhD training.

The University of Sheffield's Doctoral Development Programme supports bespoke training needs analysis for all Postgraduate Research (PGR) students, including access to masters modules across faculties/disciplines and generic research and career skills training.

Excellent collaborations with key departments

We have strong and constant collaborations with other University departments and especially the 5 departments who provide supervisors for this PhD programme.

National and international research networks

Sheffield has joint research programmes and networks with leading Universities across the UK and globally.

Commissioned work from policy and research bodies

Funding bodies currently supporting our research to address key policy questions in Public Health Economics and Decision Science:

  • Government departments in the UK
  • National Institute for Health and Care Excellence (NICE)
  • Public Health England (PHE)
  • National Institute for Health Research (NIHR)
  • Medical Research Council
  • Economic and Social Research Council
  • Research charities e.g. Cancer Research UK
  • EU Framework Programme

We make a difference to policy and decisions

We have a track record of impactful evaluations and appraisals of public health policies whilst simultaneously driving forward methodological development.

The example of alcohol pricing
The Sheffield Alcohol Policy Model (SAPM) has provided the key evidence on minimum unit pricing, drinking guidelines and other alcohol policies since 2008. It is used by the UK government, devolved administrations and international governments (e.g. Scotland, Wales, Northern Ireland, Republic of Ireland and in Canada) for policy impact assessment and decision making. Results and methodological articles have been published in world leading journals (e.g. Lancet, BMJ). Our researchers have fully engaged in policy development and analysis to inform government decisions e.g. through reports to governments, attending as witnesses at Parliamentary Select Committees, interviews on the TV, radio, news and media and engaging in public debate.

Use and develop existing policy models

ScHARR has developed and owns the Intellectual Property on a series of public health economic decision models like the Sheffield Alcohol Policy Model. Students will be able to access, utilise and further develop this infrastructure.

Have a look what the referees judging the programme proposal said

  • “The proposed training is in public health economics and decision science (PHEDS) to assist complex decisions on interventions to reduce chronic disease, trade-offs between competing priorities and cost-effectiveness of resource allocations. These are important and difficult issues for which there is needed expertise, and the program would be unique.”

  • “The cadre of potential supervisors is excellent, with diverse, but interrelated, expertise distributed among the faculty. It is likely that all students at intake will be able to identify at least one, and probably more, supervisors who will align with their research interests.”

  • “I particularly like the proposed plans for supervisor and topic selection. Students will receive continual multidisciplinary mentorship and be encouraged to pursue research that addresses relevant and complex public health challenges. The long list of distinguished faculty advisors is both impressive and consistent with the overall aims of the program.”

  • “The institutional commitment is excellent.”
Year One

Year one training will embed Wellcome Trust Scholars in ScHARR’s interdisciplinary, team-based research culture. The cohort will develop interdisciplinary grounding and methodological skills through taught masters modules. Students will receive generic research skills training, engage with public health decision-makers, and 'road-test' potential supervisors and topics during three research attachments. Finally, together with the programme directors they will select a supervisory panel and generate a detailed research proposal outlining the planned PhD work for years two to four.

Induction, mentors and training needs analysis (month one)
There will be an induction session at the start of the programme to ensure students are aware of the range of University services available to them. There will also be a social event so students can meet each other, Programme Directors and potential supervisors.

Wellcome Trust 2018 Induction                                 

                                                                                     Wellcome Trust Induction September 2018 - Cohort 3 Meets Cohort 1 & 2

All students will be assigned two Programme Directors to support them in Year 1. With their tutors, students will discuss their aspirations and expectations, undertake a formal training needs analysis and devise a personal timetable of 4 taught masters modules, generic skills training, and research attachments. Training for students from mathematical disciplines will focus on public health, while students with health-related backgrounds will focus on economics and mathematical modelling.

To assist students in deciding with whom they would like to undertake their research attachments, a seminar will be held for potential supervisors to introduce their research area to students.

It has been great to have a year to learn new skills and work with different people in the department before deciding on a research topic.

Colette Kearney, Cohort 2

Research attachments
Students will undertake three eight-week research attachments with different potential supervisors, joining their teams/project groups when not in lectures and seminars. Students will explore a number of potential PhD research topics and plans in each attachment.

Research proposals
Towards the end of year one, students will develop a detailed research proposal in one of the topic areas they explored, and supervisors and tutors will be available to provide guidance in topic and supervisory panel choice.Kearney, Cohort 2

Years Two to Four

Supervision years two to four
Quality supervision is crucial to the postgraduate experience. We are committed to ensuring excellent standards, incorporating best University practice. Training needs analyses will be revised and agreed with supervisors and a Programme Director each year. As students develop, supervisors will identify further training opportunities, assess progress, discuss career aspirations and identify ways to maximise potential.

Student progress will be carefully monitored with:HESG 2019

monthly student-led supervision meetings, with student-drafted agendas, meeting notes and next objectives
6-monthly thesis planning meetings
examination on a 10,000-word confirmation report by viva.

Year two
From year 2, students and supervisors will plan academic research visits, external courses, conference attendances, and possible internships with research-relevant external organisations. Relevant national conferences include, for example, the Lancet public health conference, the Health Economics Study Group (HESG), and the UKCRC meetings. International meeting attendance relevant to PhD topic will be agreed with supervisors. Travel grant applications will be considered by Programme Directors.

Year three
During year 3, students are encouraged to organise their own internship (up to 3 months) at a stakeholder/research organisation (e.g. the NHS, NICE, Local Authorities, Public Health England, government departments, WHO, industry, and centres of recognised scientific excellence). Students will work collaboratively with these academics and decision-makers, enabling further research translation and impact.

Year four
Year 4 students will concentrate on thesis submission, viva and academic publications. Supervision support is particularly intense during this period. The draft thesis will be read and commented on by all supervisors in the supervisory panel. We also run mock examinations to support viva preparation.

Cohort One


Tom Bayley                                                 Tom Bayley

In 2015 Tom graduated from the University of Warwick with an MMath degree. During his degree he specialised in mathematical modelling and statistics, and took a particular interest in modelling of biological systems and processes. For his Masters project he explored a stochastic model of Malaria spread. Alongside his degree he also spent time at the Anthony Nolan institute investigating geographic trends in the genetic data stored in their database of donors. 

During the first year of the Wellcome Trust programme, Tom was exposed to a wide range of topics within Public Health and Health Economics via both taught modules and research attachments. In particular, he completed taught modules in Sociology of Health and Illness, Economic EvaluationKey Issues in Global Public Health, and Contemporary Health Psychology and Behaviour Change. Tom's year one research attachments investigated using simulation modelling to assess consistency of outputs to incorporate aversion to health inequalities, the effect of parenthood on drinking habits, and agent-based modelling of obesity dynamics within an obesogenic system. Tom's experiences on these modules and research attachments has shaped the development of his PhD.

Title of PhD: The relationship between obesity and depression and the influence of socioeconomic position. Supervisors: Mark Strong, Sam Caton, Paul Bissell

Tom's research interests lie in exploring the interaction between physical and mental health as well as how these are both affected by the wider determinants of health. In particular, in his PhD he is interested in researching the complicated and complex relationships that exist between obesity, depression and socio-economic position. To do this, he is using both Structural Equation Modelling and Agent-based modelling techniques. Specifically, he is building a Structural Equation Model to explore the mediating mechanisms that might exist between obesity and depression, and whether socio-economic position interacts with these mechanisms. Within his agent-based model he is exploring whether stigmatisation might generate socio-economic inequalities in obesity and depression.

Supplementary to Tom's research project the Wellcome Trust DTC has also cultivated an interest in the use of research for public policy, as well as a greater interest in the development and implementation of Public policy more generally.

To has presented at the British Psychological Society Annual Conference 2019 on How does stigma generate socio-economic inequality in obesity and depression: an agent-based modelling study.



Sarah BatesSarah Bates

Sarah completed a Psychology degree at the university of Surrey in 2012 and a MSc in health psychology at King’s College London in 2015. Between studying she has worked as a research assistant on a range of clinical trials relating to diabetes, cardiovascular disease, lung disease and dissociative seizures. Sarah's research interests are health behaviour change, public health economic modelling and determinants of weight loss maintenance. She is also interested in how psychological theory can inform health economic evaluations.

In her first year, Sarah undertook research attachments looking at public support for public health policies, the relationship between diet and other health behaviours, and the causal relationship between wellbeing and health behaviour. She completed modules in Economic Evaluation, Cost-effectiveness Modelling, Advanced Simulation Methods, Valuing the Benefits of Health Care, and Medical Statistics and Evidence Synthesis.

Title of PhD: The Feasibility of Including Psychological Factors in Health Economic Models of Obesity. Supervisors: Alan Brennan, Paul Norman, Penny Breeze

Sarah is examining the psychosocial factors associated with weight trajectories during and after a weight-management intervention and investigating the impact of including relevant psychological factors within a health economic model of obesity on estimates of cost-effectiveness. 

Sarah has received training in Decision Modelling using R, Structural equation modelling in mplus, Latent growth curve modelling in mplus, and Laying the foundations for effective writing. She has also presented a poster at the Lancet Public Health conference.

Sarah has published the following paper:

Bates, S., Holmes, J., Gavens, L., de Matos, E.G., Li, J., Ward, B., Hooper, L., Dixon, S. and Buykx, P., 2018. Awareness of alcohol as a risk factor for cancer is associated with public support for alcohol policies. BMC public health, 18(1), p.688

"The programme provides so many opportunities alongside continued support and encouragement from developing a research idea to carrying out the research. Since starting the programme I’ve had the opportunity to learn a new discipline, practice research skills, present at conferences and gain teaching experience. I’ve met decision makers from a range of organisations, been able to collaborate with a team at another university and completed an internship abroad to gain a different perspective on my research area".

Simon McNamaraSimon McNamara

Simon's work is primarily focused on inequalities in health, and, in particular, the way in which inequalities are captured within economic evaluation in health. Prior to joining Sheffield, Simon spent six years working as a Health Economist within the pharmaceutical industry. He holds an MSc in Behavioural Science from the London School of Economics and Political Science, an MSc in Health Economics from the University of York, and a BSc in Economics from the University of York. Simon's research interests are Equity/efficiency trade-offs in economic evaluation, The valuation of subjective well-being, The role of emotion in choice experiments.

Simon undertook three research attachments in his first year. These covered: the measurement and valuation of outcomes in Public Health, the relationship between alcohol and subjective well-being, and differing approaches to considering inequalities in health when making resource allocation decisions. In addition, he has took four masters levels modules in Public Health: The Social Determinants of Inequalities in Health, Health Needs AssessmentHealth Psychology, and Key Issues in Global Public Health.

Title of PhD: How averse are the UK public to inequalities in health between socioeconomic groups? Supervisors: Aki Tsuchiya, John Holmes

Simon's PhD is focused on public preferences regarding the reduction of inequalities in health relative to the promotion of population health, and subsequently, the way in which inequalities in health are captured in economic evaluation in Public Health.

Simon has recently presented two papers at conferences. The first of these was a systematic review he undertook for his PhD. The second was a paper based upon his first empirical study. He is currently in the process of preparing these conference papers for journal submission. As a result of this work, he has been invited to visit three other universities, in order to discuss his ideas and share his work with others.

"I like being in control of my own research program. A lot of PhD funding is attached to specific projects, and, as a student, you might not have that much of say in where the research goes. On the Wellcome programme you have the opportunity to spend a year looking into the field, and working out where you think further research would be valuable, before instigating your own research program. This is really empowering, and means you have the flexibility to try things that other people might not have thought of".

Rob SmithRobert Smith

Rob studied for his undergraduate and postgraduate degrees in Economics and Applied Economics at the University of Nottingham. Upon completion of his MSc dissertation he worked for the professional services firm PricewaterhouseCoopers with several big multinational clients, after which he took up a position at the Nottingham Business School as part of a cross-disciplinary team conducting a health services research evaluation of the Prime Minister’s Challenge Fund schemes in the North Midlands. After completion of the project he worked briefly at Newcastle University, establishing a contingent valuation methodology for the valuation of both personal and public health initiatives for NHS England. His current research interests are aligned to the interaction between public health schemes in the community/primary care and demand for secondary care services.

Rob has undertaken modules in ScHARR in cost-effectiveness analysis for Health Technology Assessment, Advanced Simulation Methods, Further Statistical Methods for Health Economic Evaluation, Epidemiology, and Health Psychology. He also undertook a short course in decision analytic modelling in R, a commonly used software environment which he is using to build his model. Rob also teaches Epidemiology and Advanced Simulation Methods.

Title of PhD: Modelling school-based interventions to increase physical activity levels in children and young people. Supervisors: Liddy Goyder, Hazel Squires

Rob's PhD is focused on developing the methods utilised to estimate the health benefits and costs associated with changes in population physical activity levels. The thesis is focused on the creation of a health economic model named PACEM – Physical Activity in Children Economic Model. The model is a microsimulation model which estimates the long-term health and cost implications of interventions which affect childhood physical activity levels.

In 2018, Rob spent four weeks working with the WHO-Europe Health Economic Assessment Tool team in Zurich. He produced a report which is being reviewed by the steering group and has potential to lead to further development of modelling methods in physical activity and potentially further collaboration. This work is ongoing.

He is also collaborating with one of the Wellcome Trust Doctoral Training Centre directors and two other Wellcome Trust students on a project analysing access and utilisation to Parkrun events in England. The results may help shape Parkrun’s future strategy and has huge potential to improve public health nationwide. 

Rob has also published papers relating to Health Services and contingent valuation methodology.

She joined the University of Sheffield in 2015 as a Learning and Impact Associate on a national evaluation team for a Big Lottery Funded programme supporting individuals with multiple needs whilst mapping and influencing the systems that surround them. Multiple needs defined here as; substance misuse, homelessness, mental ill health and reoffending. In 2016 she received an NIHR studentship to study an MSc in Economics and Health Economics, a joint course delivered by ScHARR and the Department of Economics. Naomi's research interests are increasing the evidence base for alcohol policy effectiveness in LMICs, adaptability of policy decision models between countries, decision modelling as a way for key stakeholders to understand the system that surrounds the decision problem, how equity can be considered within economic decision models.

In her first year of the Wellcome Trust programme, Naomi undertook modules in Further Statistical Methods for Health Economic AnalysisEpidemiologyKey Issues in Global Public Health, and Contemporary Health Psychology and Behaviour Change

Her year one research attachments looked at the factors that support or hamper the use of health economic models within real-world public health decision-making settings, the causal relationship between wellbeing and health behaviour, and how quantitative and/or mathematical modelling approaches are employed in the emerging field of health policy and systems research in the low- and middle-income countries (LMICs),

Colette KearneyColette Kearney

Colette completed an undergraduate degree in Psychology at the University of Glasgow and a Masters of Medical Science in Human Nutrition at the University of Sheffield. Between studying and undertaking her PhD, she worked with children in the early years, teaching English as a Second Language. This role led to her interest in early years nutrition, an interest which she took forward into her Master’s degree by working with the Children’s Food Trust to evaluate their early years nutrition training for childminders. Upon completion of her Masters, she worked as a research assistant in ScHARR investigating methods to reduce the consumption of high energy dense snacks in pre-school children. Colette's research interests are within the fields of obesity prevention, childhood nutrition and public health economic modelling. She is particularly interested in methods to promote healthy eating in the early years and the impact this may have on long term health outcomes.

As part of the Wellcome Trust Programme Colette has received training in the basic principles of Economic Evaluation, Cost-effectiveness Modelling for Health Technology Assessment, decision analytic modelling and discrete event simulation. She is currently undertaking further training in qualitative research design and analysis and has begun working towards becoming an Associate Fellow of the Higher Education Academy.

Title of PhD: Grandparental influence on young children's diets and long-term health outcomes. Supervisors: Samantha Caton, Penny Breeze

Colette's PhD is exploring the role that grandparents have on the diets of children aged 2-4 and to explore whether they could be a target for intervention to improve children’s health outcomes. She will assess the acceptability, feasibility of an intervention designed to support grandparents with healthy food and drink provision and develop a decision analytic model to assess the long term cost-effectiveness of the intervention.

Colette has published the following paper:

Reale S, Kearney C, Hetherington M, Croden F, Cecil J, Carstairs S, et al. The Feasibility and Acceptability of Two Methods of Snack Portion Control in United Kingdom (UK) Preschool Children: Reduction and Replacement. Nutrients. 2018;10:1493. doi:10.3390/nu10101493.

"Coming from a psychology and nutrition background, I had very little knowledge of health economics before starting the programme. Don't let this put you off as the scheme provides you with ample training and support. It is a great opportunity to learn new skills and question how other disciplines can be incorporated into your research area".

Joseph KwonJoseph Kwon

Joseph has completed an undergraduate BA degree in Economics at the University of Cambridge and an MSc degree in Health Economics at the University of York. His previous research interest was in measurement of health utilities for childhood and adolescent populations, having published a systematic review and meta-regression of childhood health utilities.
For my PhD, I am focusing on preventive interventions to reduce frequency and severity of falls in community-dwelling elderly persons. I hope to build a public health economic model that incorporates capacity, costs and effectiveness of multi-component strategies for falls prevention, using Sheffield’s falls prevention programme as a case study.

Title of PhD: Capacity modelling of multifactorial falls prevention for community-dwelling elderly persons: cost- effectiveness of implementing an evidence-based programme in Sheffield. Supervisors: Tracey Young, Hazel Squires, Janet Harris

In Year One of the Wellcome Trust programme, Joseph undertook the following modules: Health Needs Assessment, Clinical Trials, Design of Experiments and Medical Statistics, Advanced Simulation Methods, and Key Issues in Global Public Health. The first three modules are highly relevant to his PhD: Health Needs Assessment for conceptualising the method of identifying health need (in this case, the high risk of falling) in a set environment; Clinical Trials, Design of Experiments and Medical Statistics for understanding clinical trial evidence and survival analysis both of which he will use heavily to build his statistical model; and Advanced Simulation Methods for familiarisation with building a discrete-events simulation model.

Joseph's first year research attachment was with Professor Stephen Walters and Dr Tracey Young and looked at the statistical analysis of categorical patient-reported outcomes. His findings were presented as a poster at the International Society for Quality of Life Research (ISOQOL) in Dublin. His third research attachment with Dr Pete Dodd and Dr Julie Balen was undertaken with a fellow cohort two Wellcome Trust PhD candidate, Naomi Gibbs. They systematically reviewed peer-reviewed articles that utilised mathematical models to evaluate policies and clinical interventions designed to reduce non- communicable disease burden in low- and middle-income countries. The work is still ongoing and Joseph and Naomi hope to publish the results in a top peer-reviewed journal.

At the start of Joseph's second year he attended courses on decision modelling in R, qualitative research design (interviews and focus groups) and analysis of NHS Digital's Hospital Episode Statistics, both of which are highly relevant to his PhD.

Joseph's PhD is a mixed-methods project involving both quantitative modelling and qualitative elements. Falls are one of the leading causes of disability and healthcare utilisation in the elderly - a problem which will increase with ageing population. They are also largely preventable, with many interventions such as exercise therapies to improve strength and balance, home risk modification and medication review being found to be clinically effective in reducing the risk of falling in randomised controlled trial setting. However, implementation of these interventions is poor in the real world owing to poor coordination among service providers, insufficient capacity and low participant motivation. In collaboration with Sheffield CCG and using their primary and secondary care data, Joseph plans to build a statistical model that demonstrates the cost-effectiveness of an intervention pathway that prevents falls before they lead to serious injury. He will be organising a focus group of professionals involved in falls prevention services to design an optimal intervention pathway for Sheffield, including falls risk screening, multidisciplinary assessment and individually-tailored intervention. Current users and non-users of falls prevention services among the Sheffield elderly population will also be interviewed to gain their perspective. Joseph's objective is for the model to result in evidence-based commissioning of falls prevention services at a local health authority area.

Title of PhD: Effectiveness and cost-effectiveness of sugar-reduction population-level interventions and policies. Supervisors: Jim Chilcott, Nicola Buckland

Sundus's PhD is specifically looking at investigating the short-term effectiveness of a dietary digital intervention (Change4Life Food Scanner app) in reducing children's sugar consumption through parental behaviour change. In order to achieve this, she will be undertaking a number of steps: 1) conduct a systematic review of economic evaluations and cost-effectiveness studies of childhood dietary interventions; 2) design and implement a pilot randomised controlled trial; 3) develop a dietary-focused childhood obesity prevention economic model to estimate the long term costs and health impacts of the Food Scanner app.

In 2018, Sundus did an oral presentation at the 5th UK Congress on Obesity 2018 on the relationship between meal times, calorie consumption and weight status amongst children:

 "The ScHARR Wellcome Trust programme is a unique opportunity to integrate your existing knowledge within a broader context of health. As I am from a Health Psychology background it was important to me to shift my understanding from an individual level, to tackling major health challenges such as NCDs from an upstream perspective. The programme has allowed me to develop the skills necessary to do this and I have felt supported in pursuing research opportunities including plans to attend conferences and potential future publications".

Amy ChangAmy Chang

Prior to joining ScHARR, Amy obtained a BSc degree in Pharmacy and a MSc degree in Clinical Pharmacy both at the National Taiwan University. Besides bed-side training, she has also interned at the Centre for Drug Evaluation (HTA body) in Taiwan where she performed a systematic review of the effectiveness of target therapies in non-small cell lung cancer. For her Master’s thesis, she has evaluated the cost-effectiveness of a pharmacist-assisted Warfarin monitoring program. She then worked as a Research Assistant at the School of Pharmacy, National Taiwan University, where she was in charge of model adaption for drug economic evaluation projects as well as model construction for the Taiwan EQ-5D-5L tariff derivation study. She has also conducted health care utilisation and pharmacoepidemiology studies, primarily in the area of oncology and maternal health, using national health insurance claims database and survey database

In the first year of her programme, Amy is taking modules in Introduction to Health EconomicsMedical Statistics and Evidence SynthesisAdvanced Simulation Methods, and Using Policy to Strengthen Health Systems.

Besides modules, Amy has undertaken several research attachments including looking at appropriate response options in preference based outcome measures, investigating how the relationship between runner characteristics and sustained participation in Parkrun events, and is currently busy with her third attachment exploring the impact of uncertainty in health economic decision models.

In her first year Amy has received training in Data Manipulation and Visualisation in R, and Causal Inference Affected by Treatment Switching. She has also assisted in manuscript preparation for her first attachment regarding response options and submitted a conference abstract about sustained participation in Parkrun events upon completion of her second attachment.

Amy has assisted organising the “Meet the Decision Maker” session for the programme and facilitated the invitation of key speakers from academic, Public Health England, local authorities, NICE, WHO, and other NGOs to share their experience in public health decision making and how research may inform public health decisions.

“The programme provides huge flexibility in terms of training opportunities (i.e. scheduled attachments at ScHARR and additional off-campus training upon request). The funding allows the training progress to be tailored to our own needs and mentors play an important role in guiding us to best allocate our resources in the first year. The programme has really stretched my limits and pushed me away from my comfort zone regarding research topics and disciplines that I used to work with. I felt privileged to meet experts and decision makers from all kinds of organisations through the network that has already been built up within the programme”
