Hoi-To Wai received his PhD degree from Arizona State University (ASU) in Electrical Engineering in Fall 2017, B. Eng. (with First Class Honor) and M. Phil. degrees in Electronic Engineering from The Chinese University of Hong Kong (CUHK) in 2010 and 2012, respectively. He is currently an Assistant Professor in the Department of Systems Engineering and Engineering Management at CUHK. Previously he has held research positions at ASU (USA), UC Davis (USA), Telecom ParisTech (France), Ecole Polytechnique (France), and LIDS, MIT (USA).
His research interests are in the broad area of optimization algorithms, network science, machine learning and signal processing. He has received a Best Student Paper Award from ICASSP 2018, and the 2017’s Dean’s Dissertation Award from the Ira A. Fulton Schools of Engineering of ASU for his thesis on network science and distributed optimization.
