I am a tenure-track Reader at the School of Mathematics in Tata Institute of Fundamental Research, Mumbai.

Broadly, my area of research interest is algebraic geometry. I am particularly interested in algebraic K-theory, algebraic cycles and motives in the context of algebraic stacks and equivariant algebraic geometry. I am currently working on problems related to cohomology of algebraic stacks.
