I am a University Professor in David R. Cheriton School of Computer Science. My research is on data management following two threads: large-scale data distribution, and management of non-traditional data (i.e., non-relational data). Currently, I am focusing on graph data and RDF data. Previously I studied object systems, image, video, XML data, and their management in a distributed environment. I am a Fellow of the Royal Society of Canada, the American Association for the Advancement of Science (AAAS), the Association for Computing Machinery (ACM), of the Institute of Electrical and Electronics Engineers (IEEE), an elected member of the Science Academy of Turkey, and a member of Sigma Xi. I was awarded the ACM SIGMOD Test-of-Time Award in 2015 (with Lei Chen and Vincent Oria), the ACM SIGMOD Contributions Award in 2006, and The Ohio State University College of Engineering Distinguished Alumnus Award in 2008. I have received Outstanding Performance Award at the University of Waterloo three times (2004, 2009, 2014). I currently serve on the Technical Advisory Committee of National Engineering Laboratory for Big Data Software of Tsinghua University, on the Advisory Boards of Hong Kong University of Science and Technology School of Engineering, and Hong Kong University of Science and Technology Big Data Institute, and on the Technical Expert Advisory Committee of City University of Hong Kong Multimedia Software Engineering Research Center
