Biography

Eleftherios (Lefteris) Karipidis received the Diploma degree (5 years) in Electrical and Computer Engineering from the Aristotle University of Thessaloniki, Greece, in 2001, the M.Sc. degree in Communications Engineering from the Technical University of Munich, Germany, in 2003, and the Ph.D. degree in Electronic and Computer Engineering from the Technical University of Crete, Chania, Greece, in 2008.

He was an intern with Siemens IC Mobile, Munich, in 2002 and with DoCoMo Euro-Labs, Munich, in 2003. He was a researcher with Telecommunications Systems Institute, Chania, from 2004 to September 2008. From October 2008 to May 2013, he was with Communication Systems Division, Department of Electrical Engineering, Linköping University, Sweden, initially as a postdoctoral researcher and from January 2010 as an Assistant Professor. In June 2013, he joined Ericsson Research, Stockholm, Sweden. His research interests are in the area of signal processing for communications and networking, with current emphasis on multi-antenna technologies for 5G wireless systems.

He participated in the European collaborative projects FP6 UBROAD & COOPCOM 
as researcher and in FP7 SAPHYRE & MAMMOET as work-package leader. He served as an Editor of IEEE Communications Letters in 2012 and as a member of several Technical Program Committees including IEEE ICASSP, Globecom, PIMRC, VTC, SPAWC, and GlobalSIP
