About

I apply model-based mathematical methods to solve complex problems in various domains, such as healthcare, automotive, renewable energies, and society. With 8 years as a Research Scientist at IBM Research, a Ph.D. in Electrical and Computer Engineering from the University of California, Santa Barbara, and a Dipl.-Ing. in Engineering Cybernetics from the University of Magdeburg, I have over twelve years of research experience in both academia and industry. My core competencies include control engineering (my PhD's emphasis), physical modelling, parameter estimation, computer vision, and reinforcement learning. I have published over 20 journal and conference papers and filed more than 10 patents in these fields. My most recent achievement was leading and delivering a three-year research project that combined these skills and technologies to detect cancer using fluorescence data from endoscopic videos. This project involved collaborating with medical experts and delivering a novel and impactful solution.
