Dr. Das obtained his Ph.D. degree from University of Calcutta in 1992 working at the Indian Institute of Chemical Biology. He has studied host pathogen interaction in Leishmania donovani, which causes the dreaded tropical disease Kala-azar.
As a post-doctoral fellow he worked on host-virus interactions at the University of California, Los Angeles (UCLA). Later, he served the same department as an Assistant Research Virologist (1994-1998). During this period he discovered a small RNA molecule (I-RNA) from Saccharomyces cerevisiae and showed its selective antiviral activity against polio and hepatitis C virus (HCV).
Dr. Das joined IISc in October 1998. His group has been studying the molecular basis of translational control of viral and cellular mRNAs. Much of his work has focused on internal initiation of translation of Hepatitis C virus and Coxsackievirus B3 RNA and lately extended to cellular RNA using p53 as model system. Dr. Das is coordinating the ‘Centre of Excellence for Research on Hepatitis C virus’ an interdisciplinary centre of the Department of Biotechnology, Government of India, involving 8 other laboratories.
He has been awarded National Bioscience Award for Career Development-2005 from Department of Biotechnology, NASI-Raliance Platinum Jubilee Award for Innovation in Application Oriented Research in Biological Sciences 2010, Ranbaxy Research Award in the field of Medical Sciences 2012 and Sir J.C. Bose National Fellowship from Department of Science and Technology 2014.
He is member of the American Society of Virology, American Society of Microbiology and Fellow of all three National Academy of Sciences in India.
