Dr. Hang Liu joined the Catholic University of America as an Associate Professor in the Department of Electrical Engineering and Computer Science in 2013. Prior to joining CUA, he had more than 10 years of research experience in networking industry and worked in senior research and management positions at several companies including InterDigital Communications LLC, Thomson (now Technicolor) Corporate Research Lab in Princeton, NJ, and NEC Laboratories America. He also led several industry-university cooperative research projects. He was an adjunct professor of WINLAB, ECE Dept., Rutgers University from 2004 to 2012. Dr. Liu has published more than 60 papers in leading journals and conferences, and received one best paper award and one best student paper award. He is the inventor/co-inventor of over 80 granted and pending international patents. He has also made many contributions to the IEEE 802 wireless standards and 3GPP standards, and was the editor of the IEEE 802.11aa standard and the rapporteur of a 3GPP work item. Hang Liu received his Ph.D. degree in Electrical Engineering from the University of Pennsylvania. His current research interests include the broad areas of wireless communications and networking, cognitive radio networks, Internet of Things, mobile computing, information-centric networking, content distribution, media streaming, future Internet architecture, network security, and network economics.
