About

Hi! I'm Jiasi Chen, an assistant professor in the Department of Computer Science and Engineering at the University of California, Riverside. I received my Ph.D. from Princeton University in 2015 (advisor Mung Chiang) and my B.S. from Columbia University. My hometown is the lovely city of Halifax, Canada.

My research interests include machine learning, video analytics, augmented/virtual reality (AR/VR), and mobile systems. My projects typically involve some combination of mathematical optimization and systems implementation on real testbeds. I am a recipient of the NSF CAREER award (2020), Best Paper Finalist at ACM SenSys (2019), and the Hellman Fellowship (2017). I'm also a co-founder and help advise our wonderful ACM-Women chapter here at UCR. See my CV for more details.
