My expertise lies broadly at the intersection of Genetics, Neuroscience and Psychiatry. I head the CBM Biorepository at NIMHANS, where we bank biospecimen from psychiatric patients, including stem cells, DNA, plasma and serum.

Professor, Department of Psychiatry Google Scholar | Twitter bijuv1@gmail.com Back Back to People Page Back Investigator Team Bipolar Disorder, Molecular Genetics, Stem Cell Research Dr Biju Viswanath Professor, Department of Psychiatry I am a professor of psychiatry at the National Institute of Mental Health and Neurosciences, Bengaluru (NIMHANS) , where my primary area of research includes understanding the molecular basis of etiology and treatment response in neuropsychiatric disorders. My training as a physician specialising in psychiatry and as a basic researcher in human stem cells enables me with a unique skill set to develop and execute translational psychiatry research. I am currently funded to examine genetic and cellular correlates of lithium response in bipolar disorder. I am also a key investigator at the Rohini Nilekani Centre for Brain and Mind at NIMHANS (previously the Accelerator program for Discovery in Brain disorders using Stem cells (ADBS) program funded by the Department of Biotechnology), which aims to build a biorepository of human induced pluripotent stem cells for serious mental illnesses in India. The proposed study is in line with my interests in the genetic basis of bipolar disorder. I have established a network of investigators in India that has the capability to become an important contributor in the field of psychiatric genetics.

Senior Professor Dpt. Of Psychiatry Google Scholar Back Back to People Page Back Co-Investigator Team Molecular Genetics Dr Sanjeev Jain Senior Professor Dpt. 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.
