Profile

I am an Infectious Diseases Clinician Scientist with a programme of research centred around clinical discovery science in the UK and Africa. Our group applies a broad range of methods including human immunology, epidemiology, molecular diagnostics and genomics, to establish how pathogens interact with human hosts at population and individual levels. We work primarily on respiratory viruses such as influenza and SARS-CoV-2, and Streptococcus pyogenes (Group A Streptococcus), investigating the natural history of infection and immunity to inform the design of diagnostic tools, vaccines, and other preventative measures. A specific area of interest is also how immunocompromising conditions such as HIV and haematopoietic stem cell transplantation impact the clinical risk and vaccine-induced immunity to respiratory viruses.

I am part of the Clinical Infection Research Group (CIRG) in the Medical School at the University of Sheffield and am an Honorary Consultant Physician in Infectious Diseases in the South Yorkshire Regional Department of Infection and Tropical Medicine in Sheffield. I am co-director of the Florey Institute of Infection and lead the host-pathogen interactions theme. I am also a Principal Investigator in the Vaccines and Immunity Theme at the Medical Research Council Unit The Gambia at the London School of Hygiene and Tropical Medicine.

I completed my undergraduate medical training at the University of Bristol in 2000. Following postgraduate clinical training in General Internal Medicine, Infectious Diseases and HIV in Oxford and London, I moved to Sheffield for higher specialist training in Infectious Diseases & Microbiology in 2004. After relocating to The MRC Unit The Gambia in 2007, I was awarded a British Infection Society Research Fellowship (2007-8), followed by a MRC Clinical Research Training Fellowship and PhD (2008 – 11) under the supervision of Professor Sarah Rowland-Jones and Professor Robin Weiss, to study the pathogenesis of HIV-2 infection and the molecular epidemiology of HIV-1 and HIV-2 in West Africa.

I joined the University of Sheffield in 2013 as an NIHR Academic Clinical Lecturer in Infectious Diseases & Microbiology. I was awarded a Wellcome Trust Intermediate Clinical Fellowship (2016 -2021), based between Imperial College London and the MRC Unit The Gambia, to study the immunogenicity of intranasal Live Attenuated Influenza Vaccine in children and bidirectional interactions with nasopharyngeal microbiota. I returned to the University of Sheffield as a Senior Clinical Lecturer in 2020 and led a programme of SARS-CoV-2 research through the COVID-19 pandemic, including roles as lead PI in Sheffield for the COG-UK consortium and the PITCH study. I was awarded an MBE in 2021 for services to COVID-19 research.

Teaching interests: I am involved in delivering the undergraduate (MBChB) Infectious Diseases, Tropical Medicine and Microbiology curriculum at the University of Sheffield. I also lecture on the MSc in Antimicrobial Resistance (MED404), Molecular Medicine MSc (MED6006) and Pharmacology of Respiratory Disease (CDL302, Biomedical Science).

Research themes and key projects

Mucosal and systemic immunity to respiratory viruses

Hybrid immunity to SARS-CoV-2 in Zimbabwean adults with HIV and other chronic diseases (Bill and Melinda Gates Foundation, 2023 – 2026). Key collaborators: Professor Sarah Rowland-Jones, Professor Katharina Kranzer, Professor Andrew Prendergast.
Study of SARS-CoV-2 systemic and mucosal immunity within a household transmission study in The Gambia (UKRI). Key collaborators: Prof. Beate Kampmann, Professor Adam Kucharski.
Study of SARS-CoV-2 T-cell and antibody responses as part of the PITCH study, OCTAVE study and IMMPROVE consortium (2024 – 2028).
Part of a consortium to establish a Global Paediatric Cell Atlas of Nasal and Oral Mucosa (Chan Zuckerberg Initiative, 2021 – 2025).
Supervisor for Dr. Ben Lindsey, Wellcome Trust 4ward North Clinical PhD fellowship on inflammatory memory in the upper respiratory tract following respiratory viral infections (2023 – 2026).

Epidemiology of respiratory viruses

Surveillance for SARS-CoV-2 and other respiratory viruses by establishment of a sentinel surveillance platform for influenza-like illness in The Gambia, along with a household transmission cohort (TransVir) with Prof. Beate Kampmann, Professor Adam Kucharski, Dr. Abdul Karim Sesay.
University of Sheffield lead for the COVID-19 Genomics Consortium UK (COG-UK), using Oxford Nanopore Technology (ONT) to sequence SARS-CoV-2 isolates in South Yorkshire. Building on our group’s sequencing expertise gained during this project, we are now focusing on optimising ONT-based assays with direct utility in NHS diagnostic microbiology and virology laboratories. This aligns work with key deliverables our group are leading within the Infection and Immunity Theme of NIHR Sheffield Biomedical Research Centre (BRC).

The epidemiology and immune responses to Streptococcus pyogenes

Several clinical and molecular epidemiology studies forming part of the MRC Unit The Gambia Strep A research portfolio, with Dr. Claire Turner (School of Biosciences), Prof. Michael Marks (LSHTM) and Prof Ed Clarke (MRC Gambia).

Co-supervisor for three Wellcome Trust Clinical PhD Training Fellows in Global Health (Dr. Edwin Armitage, Dr. Alex Keeley, Dr Ed Monk) who are using the platform of a household and school transmission studies to explore transmission and natural immunity to S. pyogenes.
Co-lead at the MRC Gambia in a global network of scientists seeking to define correlates of immune protection in natural infection with Streptococcus pyogenes (iSpy Network, 2023 - 2027).
Lead for immunology studies across UoS and MRC Gambia in a Wellcome Trust funded S. pyogenes human challenge study to establish correlates of protection (2025 – 2027).
