Emil Björnson

Emil Björnson was born in Malmö, Sweden, in 1983. He received the M.S. degree in Engineering Mathematics from Lund University, Sweden, in 2007. He received the Ph.D. degree in Telecommunications from the Department of Signal Processing at KTH Royal Institute of Technology, Stockholm, Sweden, in 2011. From 2012 to July 2014, he was a joint postdoc at the Alcatel-Lucent Chair on Flexible Radio, Supélec, Paris, France, and the Department of Signal Processing at KTH Royal Institute of Technology. He joined Linköping University, Sweden, in 2014 and is currently Associate Professor and Docent at the Division of Communication Systems.

His research interests include multi-antenna cellular communications, massive MIMO techniques, radio resource allocation, green energy efficient systems, and network topology design. The research builds upon theoretical tools from random matrix theory, estimation theory, signal processing, convex optimization, and multi-objective optimization. He is on the editorial board of IEEE Transactions on Green Communications and Networking since 2016, and was previously an editor of IEEE Journal on Selected Areas in Communications (JSAC): Series on Green Communications and Networking. He is the first author of the book “Optimal Resource Allocation in Coordinated Multi-Cell Systems” published in Foundations and Trends in Communications and Information Theory, 2013. He is also dedicated to reproducible research and has made a large amount of simulation code publicly available.

Dr. Björnson has 10-year experience of MIMO research and has filed a handful of related patent applications. He received the 2014 Outstanding Young Researcher Award from IEEE ComSoc EMEA, the 2015 Ingvar Carlsson Award, and the 2016 Best PhD Award from EURASIP. He has also received 5 best paper awards (as main author or co-author) for novel research on optimization and design of multi-cell multi-antenna communications: IEEE ICC 2015, IEEE WCNC 2014, IEEE SAM 2014, IEEE CAMSAP 2011, and WCSP 2009.
