Kin Cheong Sou

About

Kin Cheong Sou received his Ph.D. in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology in 2008. He subsequently held postdoctoral positions at Lund University (2008–2010) and KTH Royal Institute of Technology (2010–2013), and served as Assistant Professor of Mathematical Sciences at Chalmers University of Technology (2013–2016). He joined NSYSU in February 2017 and has been a tenured Associate Professor since February 2022. He also directs the International Master's Program in Electric Power Engineering (IMEPE) at NSYSU.

His research spans optimization modeling and analysis in power systems, uncertainty quantification for distribution networks, renewable energy integration, cyber-physical security, and battery state estimation.
