Research Interests

My research is in the area of algebraic geometry, with connections to topology and string theory. More precisely, I have studied algebraic and topological properties of parameter spaces of curves embedded in projective spaces.   Parameter spaces are sets whose elements share a number of common features. They have come to play a central role in Algebraic Geometry in recent years. For example, the geometry of parameter spaces of rational curves on a complex projective space is strongly related to such important properties of the space like rationality, unirationality or rational connectedness. In a distinct direction, counting rational curves, either via Gromov-Witten and Donaldson-Thomas invariant theories, was found by physicists working in string theory to describe observables in certain conformal quantum field theories.   In previous and current work, we explore the relation between the geometry of the parameter spaces of curves and that of the space where these curves live. For example, in joint work with Andrei Mustata, we have calculated the Chow and cohomology rings of a recently preeminent type of parameter spaces ¿ the moduli spaces of stable maps. These rings are algebraic structures encoding algebraic and topological invariants of the moduli spaces. We have shown a close, though intricate connection between the invariants of the moduli space of curves in a projective space and the invariants of the space itself. These cohomological data are generalising Gromov-Witten invariant calculations, a very active area of research in algebraic geometry.
