Biography:


Dr. Ka Wai Tsang received his B.S. and M.Phil. in Mathematics from the Chinese University of Hong Kong in 2007 and 2009, his M.S. degree in Financial Mathematics in 2011 and his PhD in Computational and Mathematical Engineering in 2015 from Stanford University, USA. His research areas include computational mathematics, financial engineering and data analytics, machine learning and time series analysis. He was a Visiting Lecturer at Stanford's Department of Statistics in the fall of 2015 teaching a new course "Data-driven financial and risk econometrics" and joined the School of Science and Engineering, the Chinese University of Hong Kong, Shenzhen in January 2016.
