Biography

Le-Nam Tran received the B.S. degree in electrical engineering from Ho Chi Minh City University of Technology, Ho Chi Minh City, Vietnam, in 2003 and the M.S. and Ph.D. degrees in radio engineering from Kyung Hee University, Seoul, Korea, in 2006 and 2009, respectively. He is currently a Lecturer/Assistant Professor with the School of Electrical and Electronic Engineering, University College Dublin, Ireland. Prior to this, he was a Lecturer at the Department of Electronic Engineering, Maynooth University, Co. Kildare, Ireland. From 2010 to 2014, he had held postdoc positions at the Signal Processing Laboratory, ACCESS Linnaeus Centre, KTH Royal Institute of Technology, Stockholm, Sweden (2010-2011), and at Centre for Wireless Communications and the Department of Communications Engineering, University of Oulu, Finland (2011-2014).

His  research interests are primarily on applications of optimization techniques on wireless communications design. Some recent particular topics include energy-efficient communications,  cloud radio access networks,  massive MIMO, and full-duplex transmission. He has authored or co-authored in some 70 papers published in international journals and conference proceedings. 
 
Dr. Tran is an Associate Editor of  EURASIP Journal on Wireless Communications and Networking. He was Symposium Co-Chair of Cognitive Computing and Networking Symposium of International Conference on Computing, Networking and Communication (ICNC 2016). He is a reviewer for many top-tier international journals on signal processing and wireless communications, and has also been a Technical Programme Committee Member for several flag-ship international conferences in the related fields.
