I had received  my post doctoral training in Gastroenterology (DM) at the Post Graduate Institute of Medical Education & Research, Chandigarh – India in 1992-93. I got my post graduate (MD) training  from the same Institute after having received my graduate degree from North Bengal Medical College. Susrutnagar, Darjeeling.  I had  received a brief training in molecular microbiology methods  at  Washington University school of Medicine, St. Louis, USA in 2000.

My  primary research  focus is in population health. As a hepatologist, this translates into studies in epidemiology and  burden of liver diseases in India.

This include the differential aspects of the  dynamics of the emerging  liver disease scenario in this country – including  population based molecular  epidemiology of  hepatitis B and C in India, characteristics of NAFLD in our population, development of  a longitudinal cohort for outcome studies in liver disease – focussing ion metabolic syndrome. In addition, I am involved in a study on Genetics of lean NASH – an entity which we have described in 2010 as a possible  “third world” NASH phenotype. I am in the board of executives of Biomedical Genomics Centre, Kolkata  and Project Director of Birbhum Population Project.

I am involved in planning and directing hepatology  clinical services at SDLD.
