Regular biography
OGUISO Keiji is a professor at The University of Tokyo, Graduate School of Mathematical Sciences, Department of MATH. His research focuses on algebraic geometry, particularly Calabi-Yau manifolds in a wider sense, including K3 surfaces, Calabi-Yau manifolds in the strict sense, and compact hyperkähler manifolds. His current work involves studying the existence problem of primitive automorphisms, the Kawamata-Morrison cone conjecture, and the (non-)liftability problem of automorphisms of K3 surfaces from positive characteristic to characteristic zero, from both birational geometrical and complex dynamical perspectives. He has published extensively in top mathematics journals, including works on birational automorphism groups, explicit examples of rational and Calabi-Yau threefolds, and non-algebraic hyperkähler manifolds.
