- Biography
Yichen Cheng is an assistant professor in Business Analytics at the Robinson College of Business’s Institute for Insight. Her research interest is in develop efficient learning methods for big data and high dimensional data, such as genomic data, text data and large scale spatial data.
Dr. Cheng obtained her Ph.D. in statistics from Texas A&M University. Before moving to Atlanta, she worked at the Fred Hutchinson Cancer research center as a post-doctoral research fellow where her research was on high dimensional data analysis with application in statistical genetics and cancer genomics.
Dr. Cheng's research has been published in premier Statistics and Business journals, including Journal of the American Statistical Association, Biometrika, INFORMS Journal on Computing, Annals of Applied Statistics and Biometrics. She currently serves as the Associate Editor of the Journal of Computational and Graphical Statistics.
At GSU, she has been teaching predictive analytics, data visualization for MSDA students and Analytics Experience for MBA students at the Robinson College of Business. She has offered multiple Bootcamps on SAS introduction, Linear Algebra and R visualization. She also leads sprints projects and work closely with companies from different industries to accommodate their needs through state-of-the-art machine learning techniques.
