Openings: Our group is looking for postdoctoral researchers, Ph.D. students and undergraduate students.


I am an Assistant Professor of Computer Science and Engineering Department in the State University of New York (SUNY) at Buffalo since 2013, where I direct the ESC (Embedded Sensing and Computing) Group. I received the Ph.D. degree from University of California, Los Angeles (UCLA) in 2013. I got both M.S. degree in 2008 and B.S. degree (both with honor) in 2006 from Zhejiang University, China.

Research Overview: Read More

Our group has focused on exploring novel Embedded Sensing and Computing technologies to build up new Internet of Things (IoT) systems for high-impact real-world applications in the fields of Wireless Healthcare, Cybersecurity and Smart Manufacturing. Results has been published in peer-reviewed top research venues across multiple disciplines, including Computer Science conferences (e.g., ASPLOS, ISCA, CCS, MobiCom, SenSys, INFOCOM and DAC), Biomedical Engineering journals (e.g., IEEE TBME, TBioCAS, and JBHI), and Medicine journals (e.g., LANCET). My group won four best paper awards, one best paper nomination and two international best design awards. My inventions have been filed within U.S. and internationally as patents, and have been licensed to several industrial players. My research has been reported in various media outlets, including the Discovery Channel, the Wall Street Journal, National Public Radio, Los Angeles Times, and the National Science Foundation's News.

Our group has been supported by National Science Foundation (NSF), National Institute of Health (NIH), National Institute for Occupational Safety and Health (NIOSH), SUNY RF, and University at Buffalo. Selected research projects are as below:

  • Wireless Health:
    • mRehab: Scalable mHealth Technologies using 3D Printing for Stroke Rehabilitation (Project Website) - Active
    • EarlySee: Pervasive Autism Screening in Infancy and Toddlerhood (Project Website) - Active
    • CSArch: Novel Architectures for Energy-Efficient Wearable Sensing (Project Website) - Completed
