Prof. Sanjeev Jain, MD, is a clinician and a teacher, and researches the genetic correlates of psychiatric and neurological disease as well as social determinant and policy issues in mental health. In addition to providing his expertise at NIMHANS, he has been involved with volunteer work with both governmental organisations and NGOs and was a member of the committee for drafting the Mental Health Policy document for India. He has been researching the history of mental health services in India, from the colonial to the contemporary period, through a grant from the Wellcome Trust, and has co-edited (with Alok Sarin) a volume on the psychological consequences of the Partition of India. This work has helped understand the interface between science and medicine, and social responses to mental illness in India. He also heads the Molecular Genetics Laboratory at the Dept. of Psychiatry at NIMHANS, which collaborates in several population and cohort studies, and also provides genetic testing for several neuro-degenerative disorders, as well as counseling services for these families. He and his colleagues have created a repository of phenotype data from carefully and comprehensively assessed subjects, detailed genetic information, and created iPSC and neuronal lines. This will enable researchers to interrogate the impact of genetic variation on various biological functions, and open up further avenues of research.
