Biography

I am an Assistant Professor in Department of Statistics, Oregon State University. Before joining Oregon State University in Spring 2015, I was a post-doctoral research scholar in Department of Statistics, University of California, Berkeley. I am also involved in projects with Life Sciences Division, Lawrence Berkeley National Laboratory. I completed my PhD in Statistics from University of California, Berkeley in 2013 under supervision of Prof. Peter J. Bickel. Before that, I completed B.Stat and M.Stat from Indian Statistical Institute, Kolkata.
