Research

I received my Ph.D. degree from the University of Illinois at Chicago (see mathematics genealogy). My research interests are algebraic geometry and commutative algebra. My current research is focused on Castelnuovo-Mumford regularity bounds, singularities under linkage of varieties, and multiplier ideals on arbitrary varities. I am also interested in problems related to generic projection, Koszul cohomology and vanishing theorem.
