[citation needed] He then joined Cornell University, where he obtained an MS and then a PhD under the supervision of Leonard Gross in 1990.

[2] Sengupta joined the Mathematics faculty of the University of Connecticut as Professor and Head of the Department in 2016.

In quantum field theory, Sengupta gave the first rigorous construction of the Yang-Mills measure for compact surfaces, with or without boundary and for bundles of specified topology.

He and Michael Anshelevich showed that the limit of the U(N) Yang-Mills measure for the plane is described by free probability theory, confirming ideas initiated by I. M.
