I am a mathematician and software engineer. I work on interdisciplinary topics in mathematics and computer science and have both deep theoretical knowledge and many years of practical industry experience. I am passionate about technology and especially interested in a human-centered and creative approach to it. As a self-motivated developer, I continuously educate myself and independently explore new technologies to find creative solutions. My own small digital lab, my bookshelf with over 300 non-fiction books, ChatGPT, supervising theses, and teaching assignments all help me. I work with a high level of responsibility and dedication and actively look for ways to improve processes and outcomes.
