Dr Christopher Rentsch


Assistant Professor
of Pharmacoepidemiology


Keppel Street
United Kingdom


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. 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


I am Program Director for pharmacoepidemiology and pharmacovigilance training at LSHTM, including:


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 epidemiological and pharmacoepidemiological research using some of the largest clinical and genetic cohorts in the world today.

I have received two prestigious awards from the International Society for Pharmacoepidemiology in 2021 (Emerging Leader Award) and 2022 (Special COVID-19 Award for "demonstrable impact on public health related to the COVID-19 pandemic"). 

I was co-Editor of a free, online textbook, "COVID-19 Real-World Evidence Primer," which aims to promote careful design and methodological approaches supporting causal inferences on drug safety and effectiveness that guide clinical and regulatory decisions.

In my spare time, you can find me performing around town in the London City Brass band.
