Li Tongzhu Job Title: Professor E-mail: litz@bit.edu.cn
My research interests are in the geometry of submanifolds (Lie sphere geometry of major submanifolds, Moebius geometry of submanifolds, Laguerre geometry of submanifolds and isometric group geometry of neutron manifolds in space of constant curvature) and the large-scale geometry of Riemannian manifolds. Presided over the National Natural Science Foundation of 4, participated in the National Natural Science Foundation of 4, participated in the Ministry of Science and Technology key research and development project. He has published more than 40 academic papers in professional journals of mathematics at home and abroad. He won one of the first prizes of the 2014 Scientific Research Outstanding Achievement Award (Nature category) of the Ministry of Education.
