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. Previously, I was an interim Professor at LMU Munich assuming the duties of Prof. Hinrich Schütze, and before that a postdoc in the Information Extraction and Synthesis Lab (IESL) at the University of Massachusetts, Amherst, working with Prof. Andrew McCallum. I did my PhD at the LSV Spoken Language Systems Lab at Saarland University under supervision by Prof. Dietrich Klakow. I am grateful for the support by a Google Europe Fellowship in Natural Language Processing for my PhD research.

My research focus lies in machine learning for relation extraction and knowledge bases. Our relation extraction system RelationFactory (on GitHub, overview, analysis) was top-ranked in the TAC KBP English Slot-Filling benchmarks, and several successful knowledge-base construction systems in TAC 2014 and 2015 were based on RelationFactory. Some of my joint work with Dr. Michael Wiegand is targeted towards entity type induction and relation extraction in the food domain. My project and work experience includes internships at Google Zurich and Xerox Research Grenoble. During my studies I worked as a programmer for the MARY text-to-speech system.
