Of Psychiatry Sanjeev Jain is a clinician and a teacher, and researches the genetic correlates of psychiatric and neurological disease. He studied medicine at the Delhi University (Maulana Azad Medical College); and did his post-graduate studies at the NIMHANS. He has been a Commonwealth Fellow at Cambridge (UK), and the co-Director of a NIH-Fogarty training and mentorship program. He has provided the lead for, and participated in, several population and cohort studies, and also provides genetic testing for several neuro-degenerative disorders, as well as counseling services for these families. This work includes the genetics of schizophrenia, bipolar disorder, Alzheimer’s disease and Huntington’s disease, as well as addiction and OCD. Over the past few years, discussions and collaboration with other colleagues at NIMHANS, the NCBS and inSTEM, have extended the research from the clinic, to the bench, using both clinical assessments (including MRI, EEG etc.) as well as tools of cellular and molecular biology, including WES, iPSC and neuronal cell lines from individuals diagnosed to have psychiatric illnesses, and their affected and unaffected relatives. He has been a member of the committee for drafting the Mental Health Policy document for India; and is also an Adjunct Faculty at the National Centre for Biological Sciences (TIFR), Bangalore. His other interests include the history of mental health services in India, from the colonial to the contemporary period. This work has helped understand the interface between science and medicine, and social responses to mental illness in India. The work has been supported by various funding agencies in India (DBT, ICMR, DST and the CSIR), as also the Wellcome Trust, NIH (Fogarty) and the MRC-ICMR.
