Dr Lee Mong Li is a Professor of Computer Science at the National University of Singapore. She has extensive experience in data management, including data cleaning and data fusion (integrating data from disparate sources), and in analysis of semistructured and spatio-temporal data. She has published more than 150 papers in major database conferences and journals, and is the co-author of two books on ``Designing Semi-structured Database'' and ``Temporal and Spatio-Temporal Data Mining''. She plays a key role in several multi-disciplinary government funded research projects to build systems that are practical and deployable. She is actively involved in the research community, holding various key roles and serving on the Program Committees of prestigious database and data mining conferences. Mong Li received her Ph.D., M.Sc. and B.Sc. (Hons 1) degrees in Computer Science from the National University of Singapore. She was awarded the IEEE Singapore Information Technology Gold Medal for being the top student in the Computer Science program in 1989. She was a visiting Fellow at the University of Wisconsin-Madison, USA 1999, and Consultant at QUIQ USA in 2000. She was the co-recipient of Singapore's President Technology Award in 2014. She is also a co-inventor of an AI system that uses deep learning to screen for major eye conditions (diabetic retinopathy, glaucoma suspect and age-related macular degeneration) from retinal images.
