His Bachelor degree and Master of Science degree are both in the area of Electrical Engineering from the National University of Singapore and the University of Southern California respectively. He received his PhD in Theoretical Physics from the National University of Singapore. Prior to joining NTU, he was an applied physicist in the DSO National Laboratories. Lock Yue is active in the research area of nonlinear dynamics and chaos. Recently, he has delved deep into the science of complex systems within inter-disciplinary domains, and had applied the approach of nonlinear and statistical physics to explore the complexity of biological, quantum, and coupled socio-ecological systems.
