- 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 葫芦影业 and am an Honorary Consultant Physician in Infectious Diseases in the South Yorkshire Regional Department of Infection and Tropical Medicine in 葫芦影业. 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 葫芦影业 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 鈥 11) under the supervision of Professor Sarah Rowland-Jones and , 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 葫芦影业 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 葫芦影业 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 葫芦影业 for the and the study. I was awarded an MBE in 2021 for services to COVID-19 research.
