Research interests

My main research interest is combinatorial commutative algebra with a focus on free resolutions of monomial ideals, and toric ideals. More generally, I am interested in computational aspects of commutative algebra and algebraic geometry, and have been active in using and developing Macaulay2. I am also interested in connections to algebraic geometry and tropical geometry.


I finished my PhD at Columbia University under the direction of David Bayer in 2009. From 2009 until 2011, I was a postdoc at Duke University working with Ezra Miller. My research interests are computational commutative algebra and algebraic geometry. I am originally from Silver Spring, MD and I graduated from the University of Notre Dame in 2002.
