I am an epidemiologist specialising in the use of electronic health records, with a focus on creating real-world evidence for the safety and effectiveness of medications.

I completed a PhD at the London School of Hygiene & Tropical Medicine in 2018. The PhD developed and implemented a probabilistic record linkage algorithm and software to link demographic surveillance with health records to measure patterns of HIV service utilisation in Tanzania.

Alongside a PhD, I was awarded a Postgraduate Diploma in Advanced Quantitative Research Methods with Distinction. 

I hold an MPH in Global Epidemiology from Emory University, and a BA in Sociology from The Ohio State University.

Department of Non-communicable Disease Epidemiology
Faculty of Epidemiology and Population Health

Teaching

I organise and lecture on a suite of pharmacoepidemiology short courses at LSHTM:

I also teach Advanced Statistical Methods in Epidemiology as a distance learning tutor.

Research

In my roles within the Electronic Health Records (EHR) Research Group at LSHTM and the Veterans Aging Cohort Study (VACS) at Yale University, I perform research using some of the largest clinical and genetic cohorts in the world today. I am also an active member with leadership roles in the International Society for Pharmacoepidemiology.

During the coronavirus pandemic, my research has focused on investigating potential pharmacotherapies for prevention and treatment of COVID-19, identifying disparities from testing to mortality, and quantifying excess risks for long-term outcomes among COVID-19 survivors.
