**
On Saturday, April 25, 2015, the second annual
**

Mid-Atlantic Algebraic Geometry and Combinatorics (MAAGC)

workshop was held at Drexel University.

My research interests are in algebraic and enumerative
combinatorics.
In particular, I work on problems involving symmetric functions and Macdonald polynomials,
combinatorial statistics and q-analogs,
rook polynomials, and am also interested in the zeros of polynomials and analytic functions.
I like experimental mathematics, and
often use computer algebra packages such as Maple in my research, to develop
and test conjectures.
