Hejie

He Jie received his undergraduate degree in Mathematics from the School of Mathematical Sciences at Nankai 

University from 2009 to 2013, and his doctoral degree in Basic Mathematics from the Institute of Mathematics 

and Systems Science, Chinese Academy of Sciences from 2013 to 2018, under the supervision of Researcher 

Wang Youde. In 2020, he joined the School of Mathematics and Physics at Beijing University of Chemical 

Technology, where he primarily conducts research in complex geometry and geometric analysis. 

His research results have been published in journals such as JFA, Math. Z., JGA, and JDE. 

He is the principal investigator of a National Natural Science Foundation of China (NSFC) project 

entitled Research on Twisted Calabi Flows. During his postdoctoral research, 

he worked on deep learning (but has since ceased this research). 

His current interests lie in the study of degenerate elliptic PDEs on manifolds 

and some geometric curvature flows. Welcome to exchange ideas!

I am mainly engaged in the research of geometric analysis and complex geometry, 

focusing on the following directions:

1. Liouville theorem and prior estimates of quasi-linear elliptic equations on manifolds;

2. Canonical metrics on nearly Kahler manifolds, including curvature functionals and geometric curvature flows, etc.;
