Research Interests:

Artificial Intelligence, Wireless Communication System/Network, Internet of Things (IoT). By borrowing techniques from diverse areas, including computer networks, machine learning, and signal processing, I like to explore and develop new software-hardware systems that enable the next generation of wireless communication, human-computer interaction (HCI), and ubiquitous sensing.


Short Bio:

I'm a senior researcher at Samsung AI Center (SAIC)-Montreal since 2020. Before joining Samsung, I did two-year postdoc at University of Waterloo, working with Prof. Srinivasan Keshav and Prof. Omid Abari. I received my Ph.D. in Computer Science from Northwest University, China in 2017, under the supervision of Prof. Dingyi Fang and Prof. Xiaojiang Chen.
