My CV.

I'm also on Math.StackExchange:

Math.StackExchange is a questions and answers site for mathematics.

You can visit the front page to see some of the recently active questions.

Research Interests

I'm primarily interested in studying the zeros of polynomials of a single complex variable (locating them, counting them, examining asymptotic distributions in families, etc.) from the standpoint of classical analysis.
