Personal profile
Research interests
I am an epidemiologist at the University of Bristol Medical Research Council Integrative Epidemiology Unit, UK and the University of Pennsylvania Perelman School of Medicine, USA. My research interests include pharmacoepidemiology and instrumental variable analysis. I completed my PhD, titled ‘New uses for old drugs: Investigating whether antihypertensives can be repurposed for the prevention of dementia’, at the University of Bristol, UK in 2019 and previously took a six-month secondment at GlaxoSmithKline to investigate the use of genetic evidence in drug target validation.
