My research interest is algebraic geometry. Especially, I am interested in 
birational behavior of Fano varieties, a special class of algebraic varieties. 
I have researched the Mukai conjecture, the existence of certain good models 
over some reducible varieties, and an algorithm to classify log del Pezzo surfaces 
(joint work with Kazunori Yasutake), etc. Recently, I am interested in K-stability 
of Fano varieties; I (and independently Chi Li) gave a birational interpretation 
of K-stability of Fano varieties.
