I am a street psychiatrist and clinician anthropologist in London, UK. I work as a Professor of Cultural Psychiatry at University College London & Consultant Psychiatrist at Camden Homeless Outreach Services & Islington Mental Health Rehabilitation Services. I am also a Lead Clinician for the Cultural Consultation Service Camden and Islington Community Health and Social Care Trust. In addition, I am Founding Editor and Editor-in-Chief, Anthropology and Medicine journal (Taylor & Francis, UK). My current interests include mental health dimensions of marginal groups with a focus on Caste in India. I have taught extensively in medical anthropology and cultural psychiatry programmes, at several national and international Universities, and was an advisor to DSM 5 Task Force for Cultural Formulation. I have supervised UCL doctoral and post-doctoral scholars conducting research on the cultural appropriateness of mental health theory and practice in low-income nations with a specific focus on India. More recently, I am engaged in field testing cultural psychological therapy for social defeat amongst Dalits (former ‘untouchables’), identity distress among 'upper-ed' and 'forward-ed' Castes in India, mental health dimensions of human-animal relationship, and addressing digital oppression in Human-Artificial Intelligence relationship. My work is translational, deploying anthropological theory in the clinic, and bidirectional in applying insights from socially defeated peoples in India to the London homeless-ed population. I am the recipient of 2023 Lucy Mair medal and Marsh Prize for Applied Anthropology, Royal Anthropological Institute, UK; 2022 Goffredo Bartocci Special Award (jointly with R Littlewood), by the World Association of Cultural Psychiatry in recognition of exceptional achievements in cultural psychiatry; & the 2022 Falling Walls Social Science and Humanities Winner, Falling Walls Foundation, Berlin, Germany.
