venexiaI am a senior research associate at the University of Bristol Medical Research Council Integrative Epidemiology Unit, UK and the University of Pennsylvania Perelman School of Medicine, USA.  My research focuses on how instrumental variable analysis can be used to study drug effects. 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 and previously took a six-month secondment at GlaxoSmithKline to investigate the use of genetic evidence in drug target validation.
