Efthymios Stathakis

I received the B.Sc. degree from the National Technical University of Athens in 2007 with specialization in communication systems (minor computer architecture), and the M.Sc. degree in Wireless Systems from The Royal Institute of Technology (KTH) in 2010. During the period 2007-2008, I was with the R&D department of Intracom Telecom S.A Solutions. In September 2015, I obtained my PhD degree from the Communication Theory Lab where I worked with Prof. Mikael Skoglund (main advisor) and Prof. Lars K. Rasmussen (co-advisor).

My research interests are in applied probability theory and convex optimization with application to interference management of wireless networks and cognitive radio systems.
