About Yaoqing (Lamar) Yang

Yaoqing (LamarYang (S.02-M.09-SM.09) received his B.S. degree from the Northern Jiaotong University, China, in 1983, and his M.S. degree from the Beijing Broadcast Institute, China, in 1986, both in Electrical Engineering. He received his Ph.D. degree in the area of wireless communications and networks from the University of Texas (UT) at Austin in 2006. He is now an associate professor in the Department of Computer and Electronics Engineering, University of Nebraska-Lincoln (UNL).

Dr. Yang started his tenure-track faculty position at UNL in 2006. He received the Kleinkauf New Faculty Teaching Award in 2009, and the Holling Family Distinguished Teaching Award in 2011. He worked as a teaching assistant at UT Austin from 2003 to 2005, and also worked as a research assistant sponsored by Advanced Research Program (ARP) from 1999 to 2002. He served as a lecturer at the Beijing Broadcast Institute from 1986 and 1997. In August 1997, he was a visiting scholar for a semiconductor project at UT Austin for about one year.

Dr. Yang has served as a Technical Program Committee (TPC) member for many years for numerous top ranked conferences, such as Globecom, ICC, VTC, WCNC, MSWiM, etc, and he served as a reviewer for IEEE Transactions on Wireless Communications (TWC), Vehicular Technology (TVT), Circuits and Systems for Video Technology (TCSVT), Communications Letters, etc. His current research interests lie in wireless communications and networks with emphasis on radio channel characterizations, cognitive radio networks, and statistical signal processing.
