Metabolic Psychiatry
Min Gao is an Epidemiologist and Health Behaviour Scientist focused on understanding the link between metabolic health and mental health through data science and exploring interventions that can help break this connection through modifiable behavioural strategies.
Currently, Min is leading
1) NIHR Health BRC funded clinical trial (DIME study), a ketogenic diet for patients with treatment-resistant depression.
2) NIHR ARC funded observational and genetic research to explore the associations and mechanisms linking obesity and cardiometabolic disorders with depression, using UK Biobank, Qresearch, and CPRD datasets.
3) Diabetes UK funded observational research to investigate the use of antidiabetic medications (e.g. GLP-1) for preventing depression and to inform the development of integrated treatment strategies for patients with type 2 diabetes.
Min welcomes world-wide collaborations in these research areas and accepts requests for supervision of Oxford DPhil and MSc students in relevant areas.
