About Me

I am a researcher and engineer with passion for wireless technologies, which I see as a key enabler for future technical advancements. Currently I am working at Siemens on making the world a safer place.

Prior to joining Siemens, I did my PhD in the Wireless Communications Group at ETH Zurich, Switzerland, under the supervision of Prof. Dr.-Ing. Armin Wittneben.
My research was focused on human posture detection with wireless body area networks, and indoor localization with Bluetooth LE and UWB. I have 5+ years of expertise in wireless technologies with publications at top-tier conferences (ICC, Globecom, ...).
During my B.Sc. and M.Sc. studies in Electrical Engineering at FAU Erlangen-Nuremberg, Germany, I had the chance to gain practical experience on antenna design and hardware for wireless applications as well as signal processing for radar and microwave imaging.
