My research in pure mathematics is centered on algebraic geometry, which studies the interplay between systems of polynomial equations and the geometry of their solution sets. 

After my early work, which combined birational geometry and the geometry of curves, my focus moved towards vector bundles on higher-dimensional varieties.  While a good share of my work on this topic involves its connections to (non)commutative algebra, its scope has recently expanded to include positivity, i.e. the algebraic study of when a vector bundle can have positive curvature.
