My research interests lie in the area of Commutative Algebra. My thesis was on problems related to the homological properties of the blowup algebras. I did Ph.D. under the guidance of Prof. Jugal K. Verma at the Department of Mathematics, IIT Bombay on The Hilbert coefficients and depth of Blowup algebras.

I continued doing research on blowup algebras for a while. I also studied a generalization of Hilbert-Samuel function and polynomials to the case of modules, known as Buchsbaum-Rim function, the corresponding polynomial and its coefficients. Of late, I am more interested in combinatorial commutative algebra. The aim is to understand the interplay between the combinatorial invariants associated to a graph and the algebraic invariants associated to monomial and binomial edge ideals. I am also interested in the containment problem and invariants associated with that, such as resurgence and asymptotic resurgence number.
