I am a Professor of Computer Science at the University of Potsdam. From 2007 to 2008 I was the head of the Machine Learning Group at the Max Planck Institute of Computer Science in Saarbrücken. Between 2003 and 2006, I was Assistant Professor at Humboldt-Universität zu Berlin. I was awarded an Emmy Noether Fellowship of the German Science Foundation DFG in 2003 and an Ernst von Siemens Fellowship by Siemens AG in 1996. I received a Master's Degree in Computer Science (Diplominformatiker) in 1995 and a Ph.D. (Dr. rer nat.) in 1999 from Technische Universität Berlin.
I am interested in machine learning, also known as big data analytics. Machine learning is the problem of automatically building models which explain observed systems and predict their future behavior. My current research interests lie in adversarial learning problems, in transfer learning, and in data science. In adversarial learning, an adversary exercises some control over the data-generation process; this reflects many security applications of machine learning. Transfer learning algorithms learn to perform a task, but do so using training data that reflect a different task. Machine learning has many diverse applications, and I am working on some of them: computer security (detection of malware, fraud, botnets, prevention of DDoS attacks), model-building in the sciences, embedded face recognition, and natural language processing. Here is an overview of my current research projects.
