I gained a first class honours degree in pharmacology (MSci) from the University of Bristol in 2016, during which I developed a strong passion for addiction science. During my degree I spent one year working in industry at Takeda Cambridge in the in vitro pharmacology department. I have now been awarded a 3 year scholarship from the Society for Study of Addiction to complete a PhD, in which I will be undertaking the project "Characterisation of Tolerance Development to Rewarding Effects of Opioids and the Effects of Ethanol on Reward Tolerance".

I graduated from Southampton University in 2013 with a BSc in Psychology with first-class honours. After completing a Psychology PGCE (with distinction) at Canterbury Christ Church University in 2014, I worked as a Psychology and Health & Social Care teacher in Oxford for a year. I recently completed an MSc in Research Methods in Psychology at Bristol University, working with the Tobacco and Alcohol Research Group (TARG) for my dissertation.
Using the Avon Longitudinal Study of Parents and Children (ALSPAC) and experimental studies, my PhD research will investigate the relationship between anxiety and alcohol use in adolescence and young adulthood. I am supervised by Professor Marcus Munafò and Professor Matthew Hickman.
