I am interested in algebraic geometry and commutative algebra. In my Ph.D thesis, I worked on a problem based on the toroidalization conjecture. More specifically, my research is focused on the following areas.

- Properties of embeddings of projective varieties in projective
spaces, specifically relating to N
_{p}property. - Local positivity of line bundles on varieties (Seshadri constants).
- Questions on linear systems of plane curves (Nagata and SHGH Conjectures).
- Inequalities involving the Hilbert coefficients of local rings.
- Resolution-type problems in algebraic geometry.
