I am an assistant professor for Large-Scale Data Science at the Department of Computer Science of the University of Copenhagen. I have received my Diploma degrees in Mathematics and Computer Science from the Westfälische Wilhelms-Universität Münster (Germany) and my PhD in Computer Science from the Carl von Ossietzky Universität Oldenburg (Germany).
My research interests include various topics in the field of data analysis (data mining, machine learning, algorithm engineering, ...) with applications for challenging large-scale scenarios in astronomy, text mining, energy systems, and others.
For an overview of past and current research projects, see here.
