Personal profile
Personal profile
I graduated from University of Liverpool with a PhD in Mathematical Sciences in 2015. After that, I have spent for almost two years at Beijing International Center for Mathematical Research in Peking University as a Postdoc fellow. I joined XJTLU in March 2018. My current research focuses on the intersection among the fields: nonlinear analysis, partial differential equations, calculus of variations and control and optimization theory.
Research interests
Nonlinear analysis, Partial differential equations, Calculus of variations, Control and optimization theory.
