Shigefumi Mori is working on the birational geometry of algebraic varieties. One of his main results is the 3-dimensional flip theorem, which established the 3-dimensional birational classification theory based on the work of M. Reid, X. Benveniste, Y. Kawamata, V. Shokurov, J. Kollár, Y. Miyaoka and others. He is currently interested in a fine classification of certain threefold structures, including flips, divisorial contractions, and Q-conic bundles.
