Position

I am a postdoctoral researcher since April 2012 working with Prof. David B. Dunson at the Duke University. Prior to this, I completed my Ph.D. from the University of Minnesota under the supervision of Prof. Sudipto Banerjee. I obtained my undergraduate (B.STAT) and masters (M.STAT) degree in Statistics from Indian Statistical Institute, Kolkata with a specialization in Mathematical Statistics and Probability in 2006 and 2008 respectively.

Apart from Statistics, I am interested in world cinema, literature, Indian music and travel. I especially enjoy following current affairs.
