My work is in the general area of Algebraic Geometry. This is the study of geometric objects of a somewhat more rigid nature then topological or analytical objects since they are solutions of systems of polynomial equations. My focus is on singularities, which are the peculiar places where these objects are not smooth, and on their effect on the local and global geometry of these shapes.
Among my interests are topics connected with topology (Milnor fibrations, local systems), number theory (Igusa local zeta functions), representation theory (D-modules), combinatorics (hyperplane and subspace arrangements), differential geometry (geometric stability).
