Bio pic

I am a PhD student, working with Dr. James Kirkbride and Dr. Glyn Lewis in the Division of Psychiatry at UCL. My current research focuses on social and spatial determinants of psychotic disorders, including schizophrenia. For part of my research, I am collaborating closely with researchers at the Karolinska Institutet.

My research will investigate the timing of exposure to adverse social environments in order to explore how these experiences influence the risk of developing psychotic disorders. I will be using longitudinal data available through record linkages in Sweden as well as the ALSPAC birth cohort from Bristol in order to investigate these questions.


I worked as an epidemiologist/biostatistician for the Public Health Agency of Canada, focusing on mental health and mental illness surveillance. I worked as a research and policy analyst at the Mental Health Commission of Canada. Prior to that, I held several jobs in public health, including health promotion and community development.


I completed my MSc in Epidemiology at the University of Ottawa Faculty of Medicine under Dr. Ian Colman’s supervision. My thesis research focused on early life predictors of adolescent suicidal thoughts. I also worked as a research assistant in the Applied Epidemiology Across the Lifecourse lab, where I was involved in projects investigating temporal trends in mental health, the link between use of preventative health services and mood disorders, and the links between child abuse and suicidality.

I also have a bachelor’s degree in Health Studies from Queens University and hold a post-graduate certificate in public health leadership from Concordia University College.
