Olly Bastiani I am a PhD student at the University of Bristol, studying epidemiology, with a focus on mendelian randomisation methods to investigate potential causal effects of vaping on physical and mental health. This follows a master’s degree in psychology, also at the University of Bristol, where I conducted projects investigating areas such as cannabis packaging and childhood predictors of gambling harm. I am currently collaborating with Anya on a project, using cohort data to explore the socioeconomic predictors of gambling-related harm.
