Experience:

Thomas Zemen received the Dipl.-Ing. degree (with distinction) in electrical engineering in 1998, the doctoral degree (with distinction) in 2004 and the Venia Docendi (Habilitation) for "Mobile Communications" in 2013, all from Vienna University of Technology.
From 1998 to 2003 he worked as Hardware Engineer and Project Manager for the Radio Communication Devices Department, Siemens Austria. From 2003 to 2015 Thomas Zemen was with FTW Forschungszentrum Telekommunikation Wien and Head of the "Signal and Information Processing" department since 2008. Since 2014 Thomas Zemen has been Senior Scientist at AIT Austrian Institute of Technology. He is the author or coauthor of four books chapters, 20 journal papers and more than 70 conference communications. His research interests focuses on reliable, low-latency wireless machine-to-machine communications for highly automated vehicles, sensor and actuator networks, vehicular channel measurements and modeling, time-variant channel estimation, cooperative communication systems and interference management.
Dr. Zemen is docent at the Vienna University of Technology and serves as Associate Editor for the IEEE Transactions on Wireless Communications.
