PhD, MSc, BSc
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 focused on adolescent mental health and social networks. My research interests involve applying both epidemiological approaches and innovative methods, such as social network analysis, to unravel 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 examined adolescent self-harm, with a specific focus on the role of gender and peer-friendship networks, using data from the Resilience, Ethnicity, and Adolescent Mental Health study (REACH).
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, carried out in collaboration with young people with epilepsy, their parents, and healthcare professionals, was part of the wider CASTLE (Changing Agendas on Sleep Treatment and Learning in Epilepsy) programme.
I also hold an MSc in Clinical Mental Health Sciences from University College London (UCL) and a BSc in Psychology from the University of Roehampton.
