About Me

I am an Assistant Professor in the Department of Epidemiology (with a joint appointment in the Department of Biostatistics) at Johns Hopkins Bloomberg School of Public Health, USA. Prior to this, I was a post-doctoral research fellow (mentored by Dr. Michael Boehnke) in the Department of Biostatistics and Center for Statistical Genetics at the University of Michigan, USA. I graduated with a Ph.D. from the Division of Biostatistics (advisor Dr. Saonli Basu) at the University of Minnesota School of Public Health, USA in July 2015. I completed Bachelor's in Statistics from St. Xavier's College under University of Calcutta, India in 2008, and Master's in Statistics  from Indian Statistical Institute, Kolkata in 2010. 

For my research, I am mainly interested in statistical genetics/genomics, genetic epidemiology, frequentist inference, case-control studies, trio design, and multivariate analysis. My research is aimed at developing novel statistical methods and software for identifying genetic variants influencing common human diseases. I have primarily worked on traits relevant to type 2 diabetes, cardiovascular disease risk, and orofacial clefts.

I was born and brought up in the City of Joy, Kolkata (formerly known as Calcutta) in India. After living in a joint family for more than two decades in Kolkata, I finally left for USA to pursue my dreams of getting a Ph.D. in Biostatistics. Apart from research and academics, I am interested in photography and love to travel around. I enjoy playing tennis, biking, swimming, hiking, and traveling with my husband. I love to cook and savor varied cuisines!
