Dr Gregory Hartwell


Assistant Professor

15-17 Tavistock Place
United Kingdom

I am a Clinical Assistant Professor at LSHTM working on public mental health, with particular focuses on children and young people's mental wellbeing and on the commercial determinants of health. Prior to this, my PhD investigated electronic cigarette use and smoking cessation services.

I am also a Fellow of the Faculty of Public Health (FFPH) and an honorary consultant in public health at the Office for Health Improvement and Disparities (OHID).

I was previously a public health specialty registrar in North London undertaking placements in local authorities, health protection teams and acute trust public health teams.

Prior to training in public health, I worked in the Department of Health and Cabinet Office on public health issues such as cancer and cardiovascular disease policy and national pandemic preparations.

I have taught for several years on various modules within LSHTM's MSc in Public Health, particularly 'Principles and Practice of Public Health' and 'Alcohol, Tobacco and Other Drugs'.


My main current research project involves the influence of the commercial determinants of health on public mental health (spanning tobacco/vaping, alcohol, ultra-processed food, gambling, social media and fossil fuels). Another major focus recently has been the impact of the pandemic on children and young people's mental health, including how schools are seeking to mitigate this. Other key areas of interests are health inequalities and tobacco/e-cigarettes.
