My research primarily addresses common mental disorders and substance use disorders, and focuses on the development and implementation of mental health programmes for vulnerable populations in a variety of settings. In the past, I have worked in South-East Asia, Africa and the middle-East. I have specific expertise in brief psychological interventions and am particularly interested in transdiagnostic psychological interventions. I am a mixed-methods researcher by training and have led several randomised-controlled trials. 

With colleaugues at LSHTM, and partners in Uganda and Ukraine, I lead a programme of work called CHANGE funded by the NIHR-Wellcome Partnership for Global Health Research.  The aim of CHANGE is to develop and implement a brief psychological intervention to reduce alcohol misuse and co-occurring psychological problems in conflict-affected populations. Our new intervention builds on Problem Management Plus (PM+), and we will test effectiveness and cost-effectiveness of our new intervention through two effectiveness-implementation hybrid trials in Northern Uganda and Ukraine.
