Shirshendu Chatterjee

Profile

After my PhD at Cornell University (2011), I joined the Courant Institute of Mathematical Sciences, New York University, as a Courant Instructor, where I stayed till 2014. In the Fall semester of 2014, I arrived at CUNY..

Education

I did my undergraduate (B.Stat degree, 2004) and masters (M.Stat degree, 2006) with Honors in Statistics at the Indian Statistical Institute in Kolkata, India. Then, I received an MS degree (2008) and PhD degree (2011) from Cornell University, Ithaca, NY USA, with major in Operations Research & Information Engineering and minor in Mathematics. 

Research Interests

My favorite research topics include analysis of probabilistic models that arise from questions in BiosciencesSocial SciencesPhysics and Computer Science; and Statistical Inference problems that arise from questions in Biosciences and other network data analysis.
