Overview

I am interested in the effects of drugs and alcohol on the brain and behaviour. My research has concentrated on examining both the benefits and side effects of recreational drugs on cognition, mental health and neurobiology. Through behavioural, neuroimaging studies and clinical trials, I have investigated the potentially therapeutic sides of controlled substances in clinical trials aimed at the treatment of addiction and in particularly looking at drugs such as ketamine and MDMA in combination with psychological therapies.

Research Keywords:

  • Psychopharmacology
  • Addiction
  • Treatment
  • Memory
  • Clinical Trials

Career

I completed my undergraduate degree and Ph.D at UCL, after a short time Yale University on a scholarship programme, I returned to UCL for a post-doc. Following this I worked at University of Melbourne as a visiting research fellow and returned to UCL for a fellowship and then Lectureship. I joined University of Exeter as a Senior Lecturer in May 2013 and was given a Chair in Psychopharmacology in 2015. I currently hold an Honorary Readership at University College London.

Research

Research interests

My research examines both the benefits and side effects of illicit drugs and I am interested in how childhood adversity and deprivation relate to addiction and whether treatments can modulate these processes. I use a range of techniques from experience sampling and qualitative interviews to cognitive testing and functional and structural neuroimaging (DTI and VBM). We also run clinical trials of illict drugs combined with psychological therapies in the treatment of addiction at the NIHR Exeter Clinical Research Facility.
