Explain. Demonstrate. Experiment. Inspire. The above sums up Dr. Terence Sim's teaching and research philosophy. Over the years, Dr. Sim has had the pleasure of teaching many courses - Programming Methodology, Computer Vision and Pattern Recognition, Digital Visual Effects, Theoretical Foundations of Multimedia, Analysis of Multimedia, Discrete Structures - and interacting with many talented students. He is currently teaching a graduate module called Biometrics Authentication. Dr. Sim is currently Vice Dean for Admissions at NUS, and was the Vice Dean for Communications at the School of Computing. For research, Dr. Sim explores several areas related to Biometrics and Visual Computing: Multimodal biometrics, Deepfake synthesis and detection, Facial image analysis and rendering, Continuous authentication, to name a few. He combines machine learning with physics-based modeling and graphics rendering to tackle the challenges in research. Dr Sim also provides consultancy in biometrics, which can be in the form of training, feasibility study, or technical assessment. Dr. Sim has published over 130 papers in top international journals and conferences. He is active both as Reviewer and as Senior Program Committee Member in numerous conferences. He is also an IEEE Member. He served as Second Vice President of the International Association for Pattern Recognition (IAPR) from 2021 to 2022, Editor-in-Chief of the International Journal for Pattern Recognition and Artificial Intelligence (IJPRAI) from 2020 to 2022, President of the Pattern Recognition and Machine Intelligence Association in Singapore from 2014 to 2016, and was also Vice President from 2010 to 2014. Dr. Sim also strongly believes in International Standards and served as Chairman of Workgroup 6: Cross-Jurisdiction and Societal Issues of the Biometrics Technical Committee in Singapore from 2006 to 2014. Dr. Sim considers it a blessing and privilege to have attended, and graduated from three top universities in the world: He obtained his Bachelor of Science in Computer Science and Engineering in 1990 from the Massachusetts Institute of Technology (MIT), his Master of Science in Computer Science in 1991 from Stanford University, and his Doctor of Philosophy in Electrical Engineering in 2002 from Carnegie Mellon University.
