Wray Buntine, PhD.
College of Engineering and Computer Science
Director, Computer Science program
Biography
Prior to his current appointment at VinUniversity, Wray Buntine was a full professor, foundation director of the Master of Data Science, and director of the Machine Learning Group at Monash University. Previously, he was conducting research projects at Helsinki Institute for Information Technology, NASA Ames Research Center, University of California, Berkeley, and Google. In the ’90s he was involved in a number of startups for both Silicon Valley and Wall Street. Professor Wray is known for his theoretical and applied work and in probabilistic methods for document and text analysis, social networks, data mining and machine learning. More recently he has been heavily involved in medical informatics. He will be general chair for Asian Conference on Machine Learning in Hanoi 2024. He is also co-Editor-in-Chief for the new ACM Transactions on Probabilistic Machine Learning and on several other journal editorial boards, and has been a senior program committee member for premier conferences such as IJCAI, UAI, AAAI, EMNLP, ICLR, ACML and NeurIPS. He has 18 book chapters, 48 journal articles and 81 refereed conference papers, several software products and two patents, with over 13,000 citations and a Google h-index of 49.
