Hassett works in algebraic geometry, the study of geometic objects defined by polynomial equations. Algebraic geometry is characterized by the feedback between polynomial algebra, which allows explicit computation, and geometric intuition and visualization. Hassett's interests include moduli and classification problems, rational points and arithmetic questions, rationality problems, as well as the classical geometry of curves and surfaces.
