Ph.D in Virology from University of Maryland, College Park, 2012
M.V.Sc. in Virology & Bacteriology from Orissa University of Agriculture and Technology, 2007

Research Interests/ Research Summary

My current research focuses on  virus characterization  and immunogen design (HIV-1 and Influenza) , mapping immune specificities in Indian population,establishment of animal models and validated/novel assays that will benefit  the evaluation of vaccine candidates, anti-viral drug screening and therapautics. My long standing research interest is to carry out innovative scientific research on viral agents leveraging on the expertise gained from HIV ,Influenza and Paramyxoviruses, thus creating a ' Translational and Systems virology platform'.
