Biography I am a final-year PhD student with Neil Ferguson and Anne Cori in the Department of Infectious Disease Epidemiology, funded by the Wellcome Trust. My current research focusses on the inference of viral load kinetics and epidemic dynamics using Ct-value distributions from the REACT data set, and community testing data from the UK. My previous projects have included (i) inference of the reproduction number in heterogeneous epidemics, published in the Royal Society Interface; (ii) evaluation of gravity models for spatio-temporal forecasting of epidemics and (iii) modelling malaria transmission during a mass drug administration trial to estimate the generation time of P. falciparum malaria. During my studies at Imperial, I took an 8-month break of studies to work full-time on the Covid pandemic, which included working in the World Health Organization’s Emergencies Program to set up data analytics infrastructure; working in the Imperial Covid-modelling team assessing intervention strategies in Latin America; and working for the UK Cabinet Office leading on presentation of infection indicators for briefings to senior stakeholders and ministers. In September 2020 I was seconded to the Joint Biosecurity Centre in the Department of Health and Social Care, where I lead on projects including (i) analysis of the efficacy of the Test and Trace program; (ii) modelling testing and isolation strategies in schools; (iii) forecasting the reproduction number based on age-prioritised vaccination roll-out, vaccine coverage and efficacy, and age-based transmission matricies. Prior to beginning my studies at Imperial I was a consultant at Dalberg Global Development Advisors, working with a number of clients in the global health space on projects including market-sizing, strategy development and program evaluations. I also worked at the Global Polio Eradication Initiative at the WHO headquarters in Geneva, during which time I was deployed to Papua New Guinea as an independent monitor for the global polio vaccine switch. I am a graduate of Trinity College Cambridge, where I obtained an MSc in Chemistry (1st class) and a BA in Natural Sciences (1st class).
