Biography

Professor Liyan Xie will join the Chinese University of Hong Kong, Shenzhen as an Assistant Professor in Summer 2021. Professor Xie completed Bachelor’s degree at University of Science and Technology of China with Statistics major in 2016. She will receive her Ph.D. degree in Industrial Engineering (with Statistics major) from Georgia Institute of Technology in 2021. Professor Xie has been invited to be reviewers of several top conferences, such as AAAI, ICML, Neurips, AISTATS, ICLR.

Professor Xie’s research interests include theoretical and methodological foundations of data science inspired by important applications (sensor networks and health care), with a particular interest in sequential change detection and robust hypothesis test through the lens of robust optimization.
