I am a Dickson Instructor at the University of Chicago Department of Mathematics . I obtained my Ph.D. degree at NEU in May, 2017 under the supervision of Terence Gaffney and Steven Kleiman.

I received my bachelors degree from MIT under the supervision of Steven Kleiman. Since 2008 I have been research fellow at the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences ( IMI-BAS ). I graduated from Sofia High School of Mathematics.

My research interests are in the overlap of birational geometry, deformation theory, singularity theory and commutative algebra. The main focus of my work is to study how algebraic varieties change in families by detecting the changes with the help of intersection theory - specifically, with numerical invariants such as volumes of line bundles.

I am interested in finding numerical control of various equisingularity conditions. As an application of my work on local volumes, I showed how to control numerically Whitney-Thom (differential) equisingularity for families of isolated singularities.

In the deformation theory of singularities, I proposed the notion of generalized smoothabily by introducing the class of singularities that admit deformations to deficient conormal singularities. This class contains all smoothable singularities, Cohen-Macaylay codimension 2 singularities, Gorenstein codimension 3 singularities, and determinantal singularities.

My other research interests include integral closure methods, valuation theory, asymptotics of associated primes, and their connections to singularities.

At University of Chicago I have been teaching MATH 25400 (Algebra I) and Math 25500 (Algebra II).

This June I am giving a series of lectures on resolution of singularities at the nationwide REU program run by our department.

Next year I am teaching MATH 24400 (Introduction to Algebraic Geometry).
