Research Interests:

Professor Mok’s recent works in Complex Differential Geometry revolve around bounded symmetric domains, holomorphic isometries and measure-preserving maps, rigidity problems and holomorphic geodesic cycles on Hermitian locally symmetric spaces. In Algebraic Geometry his recent works are primarily related to Fano manifolds and more generally uniruled projective varieties. He is on the editorial boards of Mathematische Annalen, Science China Mathematics and Chinese Annals of Mathematics.
