Biography

Yichen Cheng is an assistant professor at the Robinson College of Business’s Institute for Insight. Her research interest is in analysis for big data and high dimensional data from both frequentist and Bayesian perspectives.

Dr. Cheng obtained her Ph.D. in statistics from Texas A&M University with a concentration in adaptive Markov chain Monte Carlo and stochastic approximation. After the completion of her Ph.D., she worked at the Fred Hutchinson Cancer research center as a post-doctoral research fellow. At the cancer center, her research was on statistical genetics and cancer genomics.
