Dr. Zhenyu Cui's research interests are in financial derivatives pricing, stochastic processes and applied probability, stochastic volatility models and volatility derivatives pricing, Monte Carlo simulation and nested stochastic simulation, and also in financial systemic risk. His research has been funded by the Society of Actuaries. He holds a Ph.D. in Statistics, and a Master in Quantitative Finance from the University of Waterloo. He holds a Bachelor in Science in Actuarial Science from the University of Hong Kong.



Background and Early Life

Personal Life

Professor Cui, the son of medical doctors, grew up in China. His parents encouraged him to pursue a career outside of medicine so that he wouldn't have to "work nights". He chose actuarial science. As an undergraduate in Hong Kong, he lived in a residence that featured a "high table", similar to the one depicted in the Great Hall of Hogwarts Castle in the Harry Potter series. There he heard many famous speakers. Professor Cui credits a professor with encouraging him to enter academia. It was in Canada during graduate school that Professor Cui discovered how much he enjoyed research - not to mention snowboarding. After leaving the cold Northern climate, he found there was much to capture his interest in the New York metropolitan area. He has become a film buff and an avid theater-goer who sees almost every musical on Broadway. As rewarding as he finds teaching, there’s one other career that might have been his calling: Film director. Watch out Martin Scorsese!

Research

Research Interests

Professor Cui's research is in financial engineering, Monte Carlo simulation, and financial systemic risk. In particular, he is working on a new randomized unbiased Monte Carlo simulation scheme, which has broad applications in operations research and financial options pricing. He is also involved in a joint project on the study of effects of central clearing counterparty (CCP) to the overall systemic risk measures of the interbank liabilities network. He frequently applies tools from stochastic processes, Monte Carlo simulations, econometrics and network analysis in his research.
