Brief Bio

Dr. Hongxiang Li is currently an assistant professor with the Department of Electrical and Computer Engineering at the University of Louisville. Before joining UofL, he was an assistant professor at North Dakota State University from 2008 to 2011. Prior to that , he worked shortly in Intel (2006) and T-mobile USA (2008). He spent the summer of 2012 at the Air Force Research Lab in Rome, New York under the support of Air Force Summer Faculty Fellowship Program. He also spent the summer of 2013 at the NASA Glenn Research Center in Cleveland, OH under the support of NASA Summer Faculty Fellowship Program. Dr. Li received his B.S. degree from Xi’an Jiaotong University, China in 2000, his M.S. degree from Ohio University in 2004, and his Ph.D. degree from University of Washington, Seattle in 2008, all in electrical engineering. Dr. Li's general research interests are mobile communications and wireless networks. His research has been funded by NSF, NASA and Air Force. Dr Li is a senior member of IEEE. He is also the recipient of the 2012 Ralph E. Powe Junior Faculty Enhancement Award and a few best paper awards.

     July 2014: Congratulations to Dr. Siqian Liu (now with Apple) and Dr. Guanying Ru (now with AT&T Research Lab) for getting their Ph.D. degrees. Well done and good luck in California!

     March 2014: Congratulations to Dr. Bin Li for getting his Ph.D. degree, now he is an assistant professor with Northwestern Polytechnical University in China (西北工业大学).
