I studied electrical engineering and information technology at Ruhr University Bochum and graduated in 2012, obtaining the Dipl.-Ing. degree. My major area of studies was communication technology where I focused on speech signal processing and IT security.

Since October 2012, I am a research and teaching assistant at the Cognitive Signal Processing Group at the Institute of Communication Acoustics, Ruhr University Bochum, where I am pursuing my PhD as part of structured research training program (Ubicrypt).
My research focuses on the development of secure and usable audio CAPTCHAs for preventing automated abuse of Internet services. In addition, I am working on speech signal enhancement and robust automatic speech recognition for improving human-computer interaction.

I am generally interested in machine learning and pattern recognition using deep learning, where I expect several breakthroughs in the near future due to more profound insights in the research community but also simply due to the effect of Moore's law.

Besides my research activities, I am an enthusiast photographer who is crazy about (good) coffee and loves travelling to Asia.
