Michael Choi
I am an applied probabilist broadly interested in and fascinated by Markov chains, Markov processes, stochastic algorithms and their applications in a wide range of areas such as statistical physics, stochastic optimization, Bayesian statistics, information theory, game theory and theoretical computer science. I am currently an Assistant Professor at both Department of Statistics and Data Science at National University of Singapore (NUS) and Yale-NUS College. I am also affiliated with the Institute of Operations Research and Analytics (IORA). Prior to joining NUS in July 2021, I have worked at the School of Data Science (SDS) at The Chinese University of Hong Kong, Shenzhen. I graduated from the School of Operations Research and Information Engineering (ORIE) at Cornell University. My advisor is Prof. Pierre Patie. Prior to Cornell, I received my undergraduate degree in Actuarial Science at The University of Hong Kong. I currently serve as an Associate Editor (August 2023 - Present) of Statistics and Computing.
