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. Previously, he has held research positions at ASU, UC Davis, Telecom ParisTech, Ecole Polytechnique, and LIDS of MIT. Hoi-To’s current research interests are in the broad area of signal processing, machine learning and optimization, with a focus of their applications to network science. His dissertation on network science has received the 2017's Dean's Dissertation Award from the Ira A. Fulton Schools of Engineering of ASU and he is a recipient of a Best Student Paper Award at ICASSP 2018.
