Hi! I'm Jiasi Chen, an associate 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 edge computing, 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 Finalists at ACM SenSys (2019) and IEEE SECON (2020), and the Hellman Fellowship (2017). I'm also a co-founder of our wonderful ACM-Women chapter and the Equity Advisor for the Bourns College of Engineering. See my CV for more details.
