I am an Assistant Professor at Department of Statistic, The Chinese University of Hong Kong. Previously, I was a postdoctoral researcher in Industrial Engineering & Operations Research Department at Univeristy of California, Berkeley advised by Professor Xin Guo. I obtained my Ph. D. in the Department of Operations Research and Financial Engineering at Princeton University supervised by Professor Daniel Lacker and Professor Mykhaylo Shkolnikov in 2021. Prior to these, I received my bachelor's degree in Math from Tsinghua University in 2016.
I can be contacted at jiachengzhang [at] cuhk [dot] edu [dot] hk
Here is my CV.
My research focus lies in the theory of probability and stochastic optimization. I have worked on stochastic partial differential equations, especially Mckean-Vlasov type equation, partial differential equations, mathematical finance like stochastic portfolio theory and stochastic volatility modeling in the past few years.
