My research interests are in credit risk, optimal porfolio selection with regime switching, and neural network.

I received my Ph.D Degree in Mathematics from University of Science and Technology of China in 2019. My Ph.D thesis studies a class of dynamical models on credit portfolio with regime-switching and default contagion, utilizing recursive HJB system and BSDE with jumps.

I worked as a research assistant in The Hong Kong Polytechnic University from September 2018 to October 2018. Then I continue the same position from January 2019 to December 2019.

I worked as a research fellow in NUS from October 2020 to November 2021.
