### About me

I am a postdoctoral researcher at UCLA. I got my PhD at MIT, advised by Tom Mrowka.

One of the areas I work in is the study of low dimensional topology via gauge theory. In particular, my research so far has related to monopole and instanton Floer homologies of links, and their relation (via spectral sequences) to the links' Khovanov homologies.

Another area I work in is operator theory and non-commutative geometry. In this area, I study certain properties of group *C** algebras, looking, in particular, at the finite part of the *K*-theory of such groups.

Here is my CV.

(Tips to help find Math Sciences offices: The first digit of an office number is the floor number. The second digit is the hallway number. On all floors, even hallways (meaning the 2nd digit of the office number is even) run north-south, odd ones run east-west. On the sixth floor, hallway numbers that are a multiple of three (like mine) are in the western half of the building.)
