Wearables & digital biomarkers
Detecting mood episodes and early warning signs from wrist-worn sensors (actigraphy, sleep, heart rate variability, electrodermal activity, skin temperature) in bipolar disorder, depression and psychosis.
Imperial College London · London, UK
Consultant psychiatrist and applied machine-learning researcher.
I build and test AI that turns wearable and real-world health data into earlier, more precise mental-health care, with a focus on bipolar disorder and depression.
I am an NIHR BRC-funded Clinical Research Fellow at Imperial College London and an Honorary Consultant Psychiatrist in the NHS. I practise psychiatry and build the models myself, so I know what a tool must do for clinicians, and whether it actually does it.
Expertise
Detecting mood episodes and early warning signs from wrist-worn sensors (actigraphy, sleep, heart rate variability, electrodermal activity, skin temperature) in bipolar disorder, depression and psychosis.
Self-supervised pre-training, multi-task learning, deep state-space models, time-series foundation models and Bayesian modelling. Python, PyTorch, PyMC.
Linked health records and Fitbit data from the All of Us Research Program: cohorts and outcomes defined from SNOMED and ICD-10 codes, analysed inside trusted research environments (SQL/BigQuery).
Outcome definitions and labelling rules; false-positive versus false-negative costs; detection lead time against standard care; and subgroup fairness.
AI voice-assistant calls for remote symptom monitoring, retrieval-augmented assistants for evidence-grounded querying of health data, and tools designed to be callable by AI agents.
Consultant in general adult psychiatry across community mental health, intensive home treatment and early intervention in psychosis, so models are designed around real clinical decisions.
Projects
Open-source wearable AI platform for early risk detection
A four-institution team (Imperial, King’s College London, UCL, Edinburgh) building an open-source Python package and dashboard that take clinical researchers without coding experience from raw wearable data to early-risk models for depression, anxiety and psychosis. Evaluation is built in: error-cost trade-offs, lead time to detection, and fairness across age, sex and ethnicity. Co-designed with a Lived Experience Advisory Panel; the roadmap includes an LLM assistant and making the platform callable by AI agents.

About the Wellcome Mental Health Data PrizeRemote monitoring of bipolar disorder between clinic visits
A 12-month prospective study combining a wrist-worn wearable, a companion smartphone app and periodic AI voice-assistant calls to track rest-activity and speech in people with bipolar disorder, aiming to spot the early signs of a new mood episode. Sponsored by Imperial College London; data collection began in October 2026.
Funded by the NIHR Imperial Biomedical Research Centre
Study websiteWearable phenotypes at population scale
Using linked health records and Fitbit data from the US All of Us Research Program to characterise mood disorders between episodes: rest-activity patterns and their modulation by photoperiod, and cognitive functioning and its relationship with rest-activity profiles.
Two first-author preprints, medRxiv 2026
Open clinical wearable dataset and benchmark
An open dataset from Hospital Clínic de Barcelona: 157 participants with bipolar disorder, depression and healthy controls; 265 recordings of about 48 hours across illness states, with clinician-rated scales and medication. Benchmark tasks of graded difficulty with subject-level splits, gated by a de-identification check.

Background
Imperial College London, Department of Brain Sciences
Principal Investigator of HOUDINI-BD and team lead of RISE UP. Analyses of linked health records and wearable data in the All of Us Research Program to build tools for remote monitoring and early detection.
West London NHS Trust, Early Intervention in Psychosis
Diagnostic assessment, risk formulation and treatment planning for young adults with early psychosis and co-occurring mood, neurodevelopmental and substance-use conditions.
NHS Lothian, Community Mental Health, Edinburgh
Consultant responsibility for a community general-adult caseload across the care pathway, from referral triage and diagnosis to treatment and risk management; chaired multidisciplinary team meetings.
Hospital Clínic de Barcelona, University of Barcelona (remote)
Built the wearable-data preprocessing pipeline reused across the group’s later studies, and led ML development in PyTorch to detect acute mood episodes and estimate individual items of clinician-rated symptom scales, using multi-task learning and self-supervised pre-training. Funded by the Baszucki Brain Research Fund (Milken Institute); led to three first-author papers and a NeurIPS 2022 workshop paper.
University of Bologna · Hospital Clínic de Barcelona · King’s College London
Specialist training in psychiatry at the University of Bologna, including a year in the Bipolar and Depressive Disorders Unit at Hospital Clínic de Barcelona, and a visiting research post in medical statistics and machine learning at King’s College London (IoPPN).
