I am an Akademischer Rat (~assistant professor) in the area of deep learning & statistical NLP at the Center for Information and Language Processing, LMU Munich. Prior to this, I was an interim professor at LMU Munich. I obtained my PhD from Saarland University, supported by a Google Europe Fellowship in Natural Language Processing, and did a postdoc at UMass, Amherst. My research interests are the extraction of knowledge from text with statistical methods and knowledge-supervised learning.
