About me

I am a post-doctoral researcher in the Algèbre et Géométrie group at École Normale Supérieure, Paris and my mentor is Cyril Houdayer. In September 2024, I obtained a PhD in Mathematics from KU Leuven, Belgium and my supervisor was Stefaan Vaes.

My research interests revolve mainly around operator algebras and ergodic theory. During my PhD, I worked mostly on the connections between measured groupoids and von Neumann algebras. I completed my Bachelor's and Master's degrees in Mathematics from Chennai Mathematical Institute, India. 

I am originally from Kolkata, India. My mother tongue is Bengali (বাংলা) and my name in Bengali is written as সোহম চক্রবর্তী. I am a co-organiser for the Online seminar: Indians in Operator Algebras. Please write to me if you want to be part of the mailing list and/or give a talk. 

I am teaching the course Analytic Group Theory at the ENS in Spring 2026, together with Milan Donvil, Corentin Le Bars and Basile Morando. Some lecture notes can be found here.  

We are organising the Trimester on Operator Algebras: Approximations, Rigidity and Dynamics at the Institut Henri Poincaré in Paris from September to December 2026. Registrations are possible here.
