I study relative GromovWitten invariants and Tropical Geometry. I am particularly interested in enumerative problems (generalizations of statements of the form that there exists one line between two points or one conic between five points in the plane). GromovWitten theory has its origins in geometry but has very much a combinatorial feel. Tropical geometry is a simplified combinatorial model of algebraic geometry that nonetheless manages to capture much of its character.
My research is in studying the moduli spaces that are used to compute GromovWitten invariants and finding ways to package the invariants. This work overlaps with Symplectic Geometry, the study of moduli of curves, and some areas of combinatorics.
Currently, I am trying to systematize degeneration methods using ideas from tropical geometry. This will require developing the foundations of tropical intersection theory and applying them to a particular moduli space.
