Postdoctoral Researcher
Adolescent mental health and social networks
BIO AND RESEARCH SUMMARY
I am a Postdoctoral Researcher working with Dr. Jack Andrews on a project investigating peer influence effects on adolescent mental health. My research applies epidemiological approaches and innovative methods - such as social network analysis - to explore the complexities of adolescent social networks and their relationship to mental health outcomes, including self-harm and suicide.
Prior to joining Oxford, I completed a PhD in Social Epidemiology at the ESRC Centre for Society and Mental Health, King’s College London. My doctoral research focused on adolescent self-harm, examining the role of gender and peer-friendship networks through analysis of novel sociometric data from the Resilience, Ethnicity, and Adolescent Mental Health (REACH) study.
From 2017 to 2020, I worked as a Research Worker in Paediatric Epilepsy at King’s College London, where I co-led the development of the first Core Outcome Set (COS) for childhood epilepsy research. This work, conducted in collaboration with young people with epilepsy, their parents, and healthcare professionals, formed part of the wider CASTLE (Changing Agendas on Sleep Treatment and Learning in Epilepsy) programme.
I hold an MSc in Clinical Mental Health Sciences from University College London (UCL) and a BSc in Psychology from the University of Roehampton and have worked as an Honorary Assistant Psychologist within the NHS.
