About me:

Hi, I am Sagar. A final year PhD Student in the Dept. of Statistics, Purdue University. I work with Prof. Anindya Bhadra on Bayesian graphical models and their applications in cancer research. Before coming to Purdue, I got my Bachelor and Master of Science in Mathematics and Computing from IIT Kharagpur. I am from Hyderabad, India.
