His past projects include social media applications, games, virtual worlds, software development environments, and wearable augmented reality prototypes. His research contributed to products in IBM's Rational and Lotus divisions. He is a keynote speaker, panelist, and lecturer in industry and academic venues including the Game Developer Conference, the IEEE Game Innovation Conference, EclipseCon, and CSCW. He organized workshops at conferences such as CHI, CSCW, OOPSLA, FSE, and ICSE, helped manage IBM programs for academic outreach and grants.Li-Te's past work includes developing ways to help students collaborate on distributed software projects for charitable organizations (in partnership with McGill University, the University of British Columbia, Marist College, and Cystic Fibrosis Canada), applying social tagging to source code to enable shared navigation for developers (in partnership with the University of Victoria, Canada), and developing techniques to enable more effective technical presentations by programmers for programmers. He also was involved in the Jazz research project, enhancements to the Eclipse development environment that facilitates collaboration amongst a closely-knit group of developers, visualizing activity in internal and open source projects, as well as developing various features for Activity Explorer and Instant Collaboration and MoMail, a mobile email prototype for the PocketPC. Li-Te holds a PhD. in Electrical Engineering at the Multimedia Communications Laboratory at Memorial University of Newfoundland in Canada. As part of his doctoral research he developed a Windows-based application in which a user wearing a computer and equipped with a video camera collaborated with a desktop user via a shared panoramic video. He also modified the wearable computer to help people memorize piano music and learn ballroom dancing. In addition to this project, Li-Te developed a number of other networked video-based applications as part of this research. He holds an M.A.Sc. and B.A.Sc. in Systems Design Engineering from the University of Waterloo, Canada. During his Masters and PhD years, he participated in the International Space University, where he worked with interdisciplinary teams from around the world on strategic projects.
