Sajal Kumar Mukherjee

Post Doctoral Fellow, IAI – TCG CREST

My area of interest is broadly combinatorics, in particular enumerative and algebraic combinatorics and combinatorial topology. I have obtained my Ph.D. in Mathematics from Visva-Bharati University in 2019. The title of my Ph.D. thesis is “On Some Problems in Algebraic Combinatorics”. Prior to that, I have done M.Sc (99%) and B.Sc (72.12%) in Mathematics from RKMVU, Belur Math and Calcutta University respectively.
