Anirban Basak

I am an Associate Professor at the International Centre for Theoretical Sciences (ICTS) of Tata Institute of Fundamental Research (TIFR). My research interests lie in probability theory and its application in other fields. I have recently worked on random graphs and matrices, large deviations, and statistical physics. Here is a copy of my CV. I can be reached by email at anirban.basak@icts.res.in.

Prior to joining ICTS I was a postdoctoral fellow at the Mathematics department in Weizmann Institute of Science. My mentor was Ofer Zeitouni. Before that I spent two years at Duke Mathematics Department working as a visiting assistant professor.

I obtained Ph.D. from Stanford Statistics Department in June, 2014. My thesis advisor was Amir Dembo. I completed B.Stat., and M.Stat. from Indian Statistical Institute, Kolkata. In my final year of M.Stat., I wrote a dissertation on random matrices, supervised by Arup Bose.

In Fall 2024 I am teaching a (mini)-course on random matrices. Course materials can be found here.
