I am a clinical academic psychiatrist (on the GMC Specialist Register for Old Age and General Adult Psychiatry) with a focus on the development of treatments for neuropsychiatric disorders. My research spans the key components of neuroscience clinical trial methodology: conduct of proof-of-concept (PoC) biomarker-based clinical trials in surrogate populations, testing of repurposed compounds, development of stratification and efficacy biomarkers and creation of infrastructure for large-scale stratified recruitment into neuroscience experimental medicine studies and clinical trials. Clinically, I focus on the assessment and management of patients with neuropsychiatric presentations in acute medical settings.
