Biography

Roy Ka-Wei Lee is an Assistant Professor at the Information Systems Technology and Design Pillar (ISTD), Singapore University of Technology and Design. He is a faculty of the transformative Design and Artificial Intelligence (DAI) programme. Previously, he was an Assistant Professor of Computer Science at the University of Saskatchewan, Adjunct Faculty at School of Information Systems, Singapore Management University, and Research Fellow at the Living Analytics Research Centre. His research journey began at the Singapore Management University, where he had obtained the full suite of qualifications; Bachelor, Masters, and Ph.D. Degree in Information Sytems, on fully-funded scholarships from the university. His research lies in the intersection of data mining, machine learning, social computing, and natural language processing. He is particularly interested in studying user behaviours in multiple social networks, maintaining cyber social safety, and building next-generation social recommender systems for online social platforms.
