Sudeshna Bhattacharjee

Hello! My name is Sudeshna Bhattacharjee. I am a Brin Postdoctoral Fellow at the University of Maryland-College Park. My mentor is Professor Ron Peled.

Prior to this, from 15th February 2026 to 15th August 2026, I was a Senior research associate in probability at School of Mathematics, University of Bristol, working with Professor Márton Balázs, supported by his EPSRC grant 'Particle systems, growth models and their probabilistic structures'.

I completed my PhD in 2026 at the Department of Mathematics, Indian Institute of Science, Bengaluru. My PhD supervisors are Professor Riddhipratim Basu (ICTS-TIFR) and Professor Manjunath Krishnapur (IISc).

I am broadly interested in probability, with a current focus on random geometric models. During my PhD I have worked on models in the Kardar-Parisi-Zhang (KPZ) universality class including random matrices, last passage percolation, interacting particle systems, directed landscape.

You can find my detailed CV here.
