CITEC – Center of Excellence in Cognitive Interaction Technology
+LiLi – Faculty of Linguistics and Literary Studies

Since 3 March 2008 I have worked as a researcher at the Center of Excellence in Cognitive Interaction Technology (CITEC, “Exzellenzcluster 277”).

At the same time, I have been a PhD student first with Prof. Dr. Gerhard Jäger (initially Professor of Theoretical Linguistics at Bielefeld University; since summer 2009 Professor of General Linguistics at Tübingen University) and then with Prof. Dr. Jan Peter de Ruiter who is the chair of psycholinguistics at Bielefeld University.

Since March 2009, I have also been affiliated with Prof. Dr. Stefan Kopp's Sociable Agents Group, which is where my office is located now.

A computational linguist by training, my current main interest is putting linguistic theories to the empirical test. Most of my studies are based on linguistic data collections, usually text corpora.

While my background is in NLG (natural language generation) and unification grammars, I have recently broadened my horizon towards construction grammar, data-oriented parsing, latent semantic analyis, corpus linguistics, machine learning, and theories of discourse and dialogue.

In 2010, Prof. Jan P. de Ruiter and I started a new CITEC research project called, The role of syntactic priming in dialogue (short name: SynPrime). Stay tuned for more!

More practically, I am also involved in building a CITEC dialogue demonstrator system featuring the embodied conversational agent (ECA) Vince which is being developed by the Sociable Agents research group.

In the summer semester 2010, I taught the seminar Verfahren zur Repräsentation und Verarbeitung multimodaler Dokumente (Creating and processing multi-modal documents) for students in the linguistics Masters course with a specialisation in discourse modelling.

For facts about my past, please take a look at my old home pages at the Open University where I worked in Donia Scott's NLG group, or at Saarland University where I took a degree called Diplom-Linguist (something like a Master's) in computational linguistics. Or check out my ancient home page at DFKI (German Research Center in Artificial Intelligence) where I worked as a student in Prof. Wolfgang Wahlster's Intelligent User Interfaces group. I grew up in Mühlhausen, a town in Thuringia.

I have contributed to the following research projects (in chronological order): MedWis/KBS-DIAMET, VerbMobil-2, SmartKom, UNL (German text generation from the Universal Networking Language), Project HALO, Semantic Mining (aka Semantic Interoperability and Data Mining in Biomedicine Network of Excellence), CLEF-Services (Clinical E-Science Framework), and UNITIVES (full title: Routinization: What are the cognitive building blocks of syntactic structure?).

I am a member of the Association for Computational Linguistics (ACL), taking an active role in SIGGEN (Special Interest Group in Natural Languagen Generation; student Board member 2009–2010) and SIGSEM (Special Interest Group in Computational Semantics; webmaster since 2007, board member since 2010). At the same time, I happen to be a member of the mysterious Evolutionary Linguistics Association.

As a service to the natural language generation community (and as an experiment with Semantic MediaWiki), I host and maintain the NLG Wiki which currently contains the new version of the Bateman/Zock List of NLG Systems. Please contribute!

In my spare time, I am concerned about civil rights in the digital age.
