I am a Professor of Mathematics at Carnegie Mellon University. Previously, I was a Research Fellow at University of Cambridge and Churchill College, a graduate student at Princeton University under the guidance of Benny Sudakov and an undergraduate student at University of California, Berkeley, and at City College of San Francisco.

I enjoy mathematics for the ideas, pure and simple. All of mathematics is beautiful. The skeptics, who think otherwise, should check out the explanation why mathematics is natural and especially the article by Paul Lockhart on the topic.

I have written down some of the mathematics that I've done. It is available from my writing page.

For a collection of problems that interest me, follow this link.

In 2023 I organize Math Kangaroo competition for school students in Pittsburgh. Follow the link to learn more and register.
