Research Overview: Read More

Our group has focused on exploring novel Embedded Sensing and Computing technologies to build up innovative Internet-of-Things (IoT) systems for high-impact real-world applications in the fields of healthcare, security and advanced manufacturing. Results has been published in peer-reviewed top research venues across multiple disciplines, including Computer Science (e.g., ACM SenSys, MobiSys, MobiCom, UbiComp, ASPLOS, ISCA, HPCA, Oakland, NDSS and CCS), Biomedical Engineering (e.g., IEEE TBME, TBioCAS, and JBHI), and Medicine (e.g., LANCET, JMIR). Our group won 14 best paper/article awards, 3 best paper award nominations and 2 international best design awards. Our inventions have been filed within U.S. and internationally as patents, and have been licensed to industrial players. Our research has been reported in various high-impact media outlets, including the Discovery Channel, Cable News Network, the Wall Street Journal, National Public Radio, Los Angeles Times, and the National Science Foundation's News.
