I am working on geometric analysis, the interface of various nonlinear partial differential equations and differential geometry, specially complex geometry. The analytic tools include calculus of variations, higher order geometric flows and complex Monge-Ampère equations.

Here is my Curriculum Vitae.

My current research involves regularity/singularity phenomena of geometric PDEs, existence/uniqueness of critical metrics and convergence of geometric flows.

An almost list of my publications/preprints is available at arXiv and MathSciNet.

Junior Warwick-Imperial-Cambridge geometric analysis seminar. Queen Mary University of London, January 5-8, 2016.

Teaching Responsibilities:
