am currently the director of VinAI Research, VinGroup, Hanoi, Vietnam. My technical expertise and interests include probabilistic graphical models, deep generative models, Bayesian inference and machine learning, especially models for sequential and relational data, with applications in human activity/intent recognition, video understanding and natural language processing. These interests center around the challenging problem of how to make the machine better understand the humans – a problem that plays a central part in intelligent assistive technologies, personal assistance and dialogue management. Before joining VinGroup, the largest enterprise in Vietnam, I was at Google DeepMind, Adobe Research, and Nuance Natural Language Understanding Lab. I also spent almost 10 years at the AI Center, SRI International (formerly Stanford Research Institute). At SRI, I led the multi-institution research team in developing probabilistic inference technologies for understanding the user activities during the CALO project (at the time, the largest AI project in history, also known as the project that spun off Siri). Going further back in time, I was an assistant professor at Curtin University, Australia (2000-2003), Ph.D graduate in computer science (Curtin, 1998), a graduate from Hanoi University of Science, High School for Gifted Students, and a Maths Olympian (silver medal, IMO 1989).
