I received the Dipl.-Phys. in high energy physics in 2000 from Humboldt University, Berlin, Germany, in cooperation with DESY Hamburg. Since 2001 I have been with the Department of Broadband Mobile Communication Networks, Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut (HHI) and since 2004 with Fraunhofer German-Sino Lab for Mobile Communications. In 2007 I received the Dr.-rer.nat (Ph.D.) degree (on “Weyl–Heisenberg representations in communication theory”) at the Technical University of Berlin (TUB), Germany. Currently I am working under own DFG grants at TUB in the field of signal processing and information and communication theory. I am a member of the The Communications and Information Theory Group (CommIT) of Prof. Giuseppe Caire. I am also a visiting professor at TU Munich and associated with the Munich AI Future Lab (AI4EO).
