I am a Public Health doctor whose interests include

- pharmacoepidemiology, in particular psychiatric adverse drug reactions (depression, non-fatal self-harm and suicide) associated with varenicline, a smoking cessation medicine and antidepressants

- use of large primary care databases such as the Clinical Practice Research Datalink (CPRD) for observational research including novel study designs for dealing with confounding by indication such as instrumental variables and case only designs

- mental health research (suicide and self-harm) and suicide prevention

- substance dependence and addiction (prescription opioid dependence)

- trends in suicide in the UK and internationally


I am currently a Consultant in Public Health at South Gloucestershire Council (0.6FTE) and a Clinical Lecturer in Public Health at the University (0.5FTE). I completed a National Institute for Health Research (NIHR) Academic Clinical Lectureship in Public Health in October 2016 where I spent 50% of my time at South Gloucestershire Local Authority and 50% of my time at the University. I completed a NIHR Doctoral Research Fellowship in December 2013 where I examined the association between specific prescribed drugs (smoking cessation medicines and antidepressants) and psychiatric adverse drug reactions (depression, non-fatal self-harm and suicide) using the Clinical Practice Research Datalink (CPRD), formerly known as the General Practice Research Database (GPRD). I was awarded a PhD with Commendation from the University of Bristol in March 2014.

I am a Fellow of the UK's Faculty of Public Health. In addition, I completed a Certificate in Pharmacoepidemiology and Pharmacovigilance with Distinction at the London School of Hygiene and Tropical Medicine (LSHTM) in 2012. 

I am currently an Assistant Editor with the Addiction journal.

I was Public Health element lead for Community Oriented Medical Practice (COMP) for 4th year Bristol medical students from 2010-2012 and 2013-2014. I currently teach on this course.  I am also involved in teaching Clinical Epidemiology to first year medical students.

I am Public Health champion for the Global and Public Health helical theme in the new medical undergraduate curriculum (to be launched in Sep 2017).

I also participate in revision courses for public health registrars on the South West Public Health training scheme prior to the Part A examination.
