I am Reader in Mental Health and Director of Education & Deputy Director of the Wolfson Institute of Population Health. I originally trained in sociology but now work in public and forensic mental health, conducting epidemiological and health services research into the efficacy of treatments for those with mental health problems, specifically those at risk of violence or becoming victims of violence. I am also an Honorary Senior Research Fellow at East London NHS Foundation Trust and a Fellow of the Alan Turing Institute. I have recently consulted on forensic mental health issues for NHS England and the London Violence Reduction Programme, as well as films and television shows such as the BBC America drama series Killing Eve and Channel 4 prison drama Screw.

My current work includes: the epidemiology of violence; outcomes research in forensic mental health services; causal inference networks for violence risk management; clinical sub-types of personality disorder and psychopathy; substance misuse as a risk factor for violence; and patterns of service use by young men in the UK.

I have previously held grants from the NIHR and UKRI and am currently mental health co-lead for the North Thames Applied Research Collaboration (NT-ARC).


Research Interests:

  • Machine-learning algorithms to assist decision-making in management of violence risk
  • Innovative use of routine healthcare data to model mental health outcomes
  • Psychological milieu therapy and therapeutic communities
  • Clinically distinct sub-groups within psychopathy and personality disorders
  • Social climate within forensic settings
  • Psychosocial interventions for personality disorder
  • Causal mechanisms for violence
