Lindsay is an Advanced Research Fellow in mental health at the NIHR Patient Safety Translational Research Centre and Honorary Research Psychologist at West London NHS Trust. She currently leads projects examining patient safety in mental health, and her work primarily focuses on detecting youth mental health deterioration using digital devices. She has a special interest in lifestyle factors such as sleep and social connection as early prevention strategies for worsening youth mental health. Other work centres on suicide prevention, self-harm and care transitions in vulnerable and seldom-heard groups. She is also a Imperial Mental Health Research Network steering group member.

Co-production in mental health

Lindsay's works embeds meaningful patient and public involvement (PPI) and/or co-production. This usually means working together with people with lived experience of mental health difficulties throughout the research process - from prioritisation and design to dissemination. Her latest work examines the impact of COVID-19 lockdown on the mental health and coping strategies of young people which is co-produced with young people with experience of mental health difficulties. She is also leading a qualitative systematic review on this topic. 

Public engagement

Lindsay is actively involved in public engagement projects including IGHI blogs, increasing awareness in young men's mental health through creative media (Fightin' Thru) and film drama focused on inequalities and young people's mental health during the pandemic. She also led the Pint of Science 2019 Beautiful Minds session.


She is Topic Lead in Mental Health and Wellbeing for the Lifestyle Medicine and Prevention module for MBBS at Imperial. She lectures across BSc Neuroscience and Mental Health, MSc Health Policy and MSc Patient Safety courses, and supervises MSc Health Policy and BSc Neuroscience and Mental Health students.

Background and experience

Lindsay's background is in psychology (BA, MSc) and forensic psychology (MSc). During her PhD, titled: Insomnia in a prison population: a mixed methods study, she studied the prevalence and associated factors of insomnia including depression, suicidality and anxiety in a large cohort of male and female prisoners at The University of Manchester. She subsequently designed and tested a novel treatment pathway for insomnia for prisoners in a high secure prison in England after winning a Health Foundation Innovating for Improvement Award. She has over 15 years research experience that spans across public health, psychology and forensic mental health.
