Dr. Liangfeng Zhang received his bachelor and master degrees in applied mathematics from Tongji University and Shanghai Jiao Tong University, respectively. He received PhD degree in cryptography and information security from Nanyang Technological University, Singapore. He has been a postdoctoral fellow at the University of Calgary, Canada. His research interests include cryptography and coding theory. He joined the School of Information Science and Technology at ShanghaiTech University in 2015 and now is a tenured associate professor. From Sep 2017 to Dec 2017, he has been a visiting professor at UC Berkeley, USA. Recently, Dr. Zhang’s research has been focused on cloud computing security, secure multiparty computation and blockchain security, and funded by the National Natural Science Foundation of China, Natural Science Foundation of Shanghai and Shanghai Pujiang Talent Program. Dr. Zhang has been an invited reviewer of “Mathematical Reviews” (AMS) since 2016. He is on the program committee of several international conferences on information security, including ProvSec 2020, ProvSec 2021， ProvSec 2022 and ACISP 2022.
