Zitao Chen

Ayo~ I am a Ph.D. student in the ECE department at University of British Columbia (UBC), where I'm working in the Dependable Systems Lab with Prof. Karthik Pattabiraman. I received my M.A.Sc degree from UBC in 2020 and my bachelor's degree from China University of Geosciences (Wuhan) in 2018. [CV]
