Anirban Basak is a professor at the International Centre for Theoretical Sciences of the Tata Institute of Fundamental Research. Previously, he was a postdoctoral fellow in the mathematics department at the Weizmann Institute of Science, where his mentor was Ofer Zeitouni. Prior to that, Anirban spent two years in the Duke mathematics department working as a visiting assistant professor. He obtained his PhD from the Stanford statistics department in June 2014, advised by Amir Dembo.

Broadly, his research interests lie in random matrices and graphs and in statistical physics. Anirban has worked on understanding various spectral properties of sparse non-Hermitian random matrices, in particular their invertibility, condition number, and sensitivity of the spectra under small perturbations. Recently, he has been interested in studying large deviations in random graph models. Anirban has also studied some aspects of statistical physics models on sparse graphs.
