Introduction:

I am mostly interested in combinatorics (algebraic, geometric, topological), matroids and their variations, polyhedral geometry, and tropical geometry. But I am also branching out in related subjects including real algebraic geometry. I have been working on geometric objects associated with (oriented) matroids and their relation with tropical geometry, as well as Jacobians (also known as sandpile groups or critical groups) and the chip-firing game on graphs and their generalizations.
