I am an epidemiologist, with a focus on neglected tropical diseases (primarily trachoma) and sexually transmitted infections (STIs).

I obtained both my MSc (Control of Infectious Diseases) and PhD ("Trachoma control and elimination: Field studies in The Gambia and Senegal") from LSHTM, and led the field studies for the Partnership for the Rapid Elimination of Trachoma (PRET) trial in The Gambia. I also have experience of infectious disease surveillance, having been the Senior Enhanced Surveillance Scientist for CJD at Public Health England, and then a Principal Scientist in PHE's HIV/STI department. I was Senior Trials Coordinator for the eSTI2 Consortium, led by St George's, University of London, and subsequently the Programme Manager and Epidemiology Lead for the Applied Diagnostic Research and Evaluation Unit (ADREU), where I conducted several diagnostic evaluations to assess the performance, clinical and public health impacts of novel diagnostic technologies for STIs.

I returned to LSHTM in November 2017 as an Associate Professor and Chief Scientist for Tropical Data (www.tropicaldata.org), supporting national programmes to collect scientifically robust and standardised neglected tropical disease (NTD) prevalence data, allowing interventions for disease elimination to be targeted and prioritised. Through this role, I support research to principally help improve NTD survey and diagnostic methods. I also continue to be involved in STI-related research.

I represent Tropical Data as an observer of the International Coalition for Trachoma Control (ICTC) and am an observer of the Trachoma Expert Committee. I am a member of the ICTC "Hard to reach populations" Task Team, the NNN "Conflict and Humanitarian Emergency" working group, and the NNN "WASH" working group. I am also co-chair of the WHO NTD Diagnostic Technical Advisory Group (DTAG) cross-cutting sub-group on surveillance. I am co-director of LSHTM's STI Research Interest Group (https://www.lshtm.ac.uk/research/centres-projects-groups/stirig), Bristol Health Partners Sexual Health Improvement Programme (https://www.bristolhealthpartners.org.uk/health-integration-teams/sexua…), and LSHTM's WHO Collaborating Centre for STIs (https://www.lshtm.ac.uk/research/centres-projects-groups/whocc-sti).
