Dr. Yang received a PhD in Biostatistics from the University of Minnesota and a BS in Management Information Systems from Chu Kochen Honors College, Zhejiang University. Prior to joining CityU, he served as a postdoctoral research scientist in the Department of Biostatistics at Columbia University under the supervision of Professor Iuliana Ionita-Laza. He is also a four-time recepient of the First Prize in the National Olympiad in Informatics (NOI), China.
Dr. Yang's research focuses on variable selection methods for high-dimensional data using knockoff statistics, statistical machine learning, and Bayesian hierarchical models. He has developed a number of statistical methods to identify risk variants for human diseases in genetic data with complex hierarchical and correlation structures. His research is supported by the Research Grants Council of Hong Kong (RGC) Early Career Scheme 21303323 (sole PI).
