I am the Batten Chair of Cybersecurity and the Director of the Center for Cybersecurity Education and Research at Old Dominion University (ODU). I am also a Professor in Department of Electrical and Computer Engineering. Before joining ODU, I was an Alfred and Helen Lamson Endowed Professor at the Center for Advanced Computer Studies (CACS), University of Louisiana at Lafayette (UL Lafayette). I received the B.S. degree in scientific instruments from Zhejiang University, Hangzhou, China, in 1996, and the M.S. degree in electrical engineering and Ph.D. degree in computer science from the State University of New York (SUNY) at Buffalo in 2000 and 2002, respectively. Being a professor is the greatest job. I get to explore interesting ideas, interact with brilliant scholars, and mentor young people. My research focuses on networked cyber-physical systems for security, safety, and emergency management applications, where the devices are often light-weight, with extremely limited computing power, storage space, communication bandwidth, and battery supply. I received NSF CAREER Award in 2004, UL Lafayette Distinguished Professor Award in 2011, and IEEE Percom Mark Weiser Best Paper Award in 2018.
