Assoc. Prof. Lock Yue Chew is a theoretical physicist with the Division of Physics and Applied Physics of NTU. He is the Associate Chair (Students) of the School of Physical and Mathematical Sciences; and the Deputy Director of the Data Science and AI Research (DSAIR) Centre of NTU in the cluster of Complex Systems. His research interest is in the physics of complex systems. He applies statistical and nonlinear physics with machine learning and artificial intelligence techniques to investigate diverse social systems. He is also affiliated with the Complexity Institute of NTU.
I am a theoretical physicist with research interest in the Physics of Complex Systems. I aims to uncover the fundamental physical mechanisms and organization principles of complex systems. I am currently active in applying statistical and nonlinear physics with Machine Learning and Artificial Intelligence techniques to investigate diverse social complex systems. My recent research focuses on the phase transitions of the cultural system of the Balinese Subaks, and the development of physics-based AI systems to solve the complex societal problems of bus scheduling, urban planning and medical diagnostics.
Bring the insights of physics to bear on social systems so as to improve and to enhance it.
