I am a Professor of Computer Science at TU Berlin, where I head the Chair of Machine Learning and Security within the Berlin Institute for the Foundations of Learning and Data. Previously, I have been working at TU Braunschweig, University of Göttingen, and Fraunhofer Institute FIRST. Additionally, I have been a Guest Professor at TU Wien in 2024.
My research interests revolve around computer security and machine learning. My group is developing novel methods for detecting computer attacks, analyzing malicious software and discovering security vulnerabilities. Moreover, we explore the security and privacy of learning algorithms.
My Erdős number is 3 (Müller → Jagota → Erdős) and my Bacon number is ∞. I am a very distant academic relative of Carl Friedrich Gauß (see here). My weak spot is my ha-index of 65, which many of my students surpass.

For fun, I am tracking my reviewing and email activity. Here are two plots showing my reviewing activity over the last years. As you can see, I am writing a lot of reviews per year. Most of the time, this is fun.
Similarly, here are two plots showing the number of incoming and outgoing emails on my university account over the last two weeks. The average and standard deviation are calculated over several years (see week number in legend).
