I lead the Natural Language Processing (NLP) Group at HITS gGmbH, Heidelberg, Germany. There, I am involved in NLP related projects, work with the computational linguists at HITS, and supervise PhD. students. In addition, I am Honorarprofessor in the Computational Linguistics Department at the University of Heidelberg. I am a Fellow of the Association for Computational Linguistics.
Paper accepted as spotlight presentation at NeurIPS '21: Federico López, Beatrice Pozzetti, Steve Trettel, Michael Strube and Anna Wienhard: Vector-valued distance and gyrocalculus on the space of symmetric positive definite matrices. (PDF)
Paper accepted at ICML '21: Federico López, Beatrice Pozzetti, Steve Trettel, Michael Strube and Anna Wienhard: Symmetric spaces for graph embeddings: A Finsler-Riemannian approach. (PDF)
I am co-organizer for the 2nd Workshop on Computational Approaches to Discourse, CODI 2021 at EMNLP '21 held in Punta Cana, Dominican Republic, November 10-11, 2021 (the first conference which actually happens after the plague!).
I am also co-organizer for the CODI-CRAC 2021 Shared-Task: Anaphora Resolution in Dialogues at CODI '21.
Teaching winter term 2021: Discourse Processing in the CL Department at the University of Heidelberg.
I was named Fellow of the Association for Computational Linguistics in 2019.
(This isn't really news ...) According to Google Scholar the AAAI '06 and AAAI '07 papers Simone Paolo Ponzetto and I co-authored are the most cited papers of the top conference in AI (Google Scholar query for AAAI 2006 and AAAI 2007)!

Send me email if you want to get a copy of a paper not linked on these pages (in those cases we had to transfer the copyright to the respective publishers; maybe linguists should follow the good example of JAIR and start to publish in open access journals).
I received my Ph.D. from the (now defunct) Computational Linguistics Department at the University of Freiburg, Germany, in December 1996 under the supervision of Udo Hahn. Between 1997 and 1999 I was a postdoctoral fellow at the Institute for Research in Cognitive Science at the University of Pennsylvania, Philadelphia, PA. In 2000 I joined the European Media Lab in Heidelberg, Germany, as a researcher. Since 2001 I am group leader of the Natural Language Processing (NLP) Group of HITS, an institute which rapidly underwent several transformations before (hopefully) arriving at its final destination:
European Media Lab → EML Research → HITS.
Anyway, it has been a lot of fun to be here ...
In 2010 I got appointed Honorarprofessor in the Computational Linguistics Department at the University of Heidelberg.
In 2015 I was PC Co-Chair of the ACL's flagship conference ACL-IJCNLP '15 held in Beijing, China, July 26-31, 2015. We created about 3000 pages of printed paper as output.
In 2017/18 I served as scientific director at HITS.
In 2019 was named Fellow of the Association for Computational Linguistics.
