Kaikai Liu joined SJSU as an assistant professor in the Department of Computer Engineering since 2015. His research interests include Mobile and Cyber-Physical Systems (CPS), Smart Sensing, Internet-of-Things (IoT), Software-Defined Computing and Networking. He has published over 15 peer-reviewed papers in journals and conference proceedings, 1 book, and 4 patents (licensed by three companies). He developed many working systems from scratch for smart sensing, search and rescue victims, UWB, indoor localization, human-computer interaction (HCI), mobile crowd sensing and social networking, cloud computing, scientific computing and big data. He published and demoed his "Guoguo" system in ACM MobiSys2013 (top conference in mobile systems with only 32 works accepted worldwide).

He was a member in the Scalable Software Systems Laboratory (S3Lab) at the University of Florida (UF). He received a PhD degree in Computer Engineering from UF under the direction of Dr. Xiaolin (Andy) Li. He is a recipient of the Outstanding Achievement Award at UF (four times), the Apple WWDC Student Scholarship (2013 and 2014), the Innovator Award from the Office of Technology Licensing at UF (2014), the Top Team Award at NSF I-Corps Winter Cohort (Bay area, 2015), and the 2015 Gator Engineering Attribute Award for Creativity at UF (only one from the whole college). He served as the TPC member for the Data Center & Big Data track of the 24th ICCCN, technical reviewers for many IEEE/ACM transactions.
