I have been working on birational geometry of algebraic varieties. The fundamental tool in this area is the minimal model program (MMP). I am interested in topics related to Minimal Model Program (e.g., existence of good minimal models, non-vanishing conjecture, abundance conjecture, minimal log discrepancies) and properties of minimal varieties and Fano varieties (e.g., boundedness, birationality, geography, positivities, derived categories). I am interested in both exploring general theory in arbitrary dimensions and investigating explicit geometry and classification theory in lower dimensions.
