Curriculum Vitae

Team and Research Foci

I am leading the AI and Intelligent Systems group at HPI, which currently consists of 20+ staff members plus various master's and bachelor's students. We conduct interdisciplinary research in computer science and beyond. The vision driving this research is the idea that there is now so much digital data out there that machines ought to be able to learn to guide us in almost every aspect of our daily life, e.g. by addressing our information needs and helping us make more informed decisions. This, however, requires novel algorithms that simultaneously learn and integrate information from multiple heterogeneous data sources in order to make sense of human language and more generally of the world.

More specifically, my research interests include:

  • AI and Machine Learning, especially for Large Language Models and Natural Language Processing
  • Cross-modal AI, e.g. incorporating knowledge graphs, vision-language models
  • Societal and philosophical aspects of AI


Join us!

Get in touch with me if you are seeking PhD or Post-Doc opportunities at one of the top universities for computer science in Germany, located in the attractive and very international Berlin area.

Projects and Downloads

Universal Wordnet (UWN)
One of the largest multilingual knowledge graphs, transforming the well-known WordNet database into a massively multilingual resource covering over 1 million words and several million named entities in a single semantically organized hierarchy. Our derivative project OpenWN-PT is being used by Google Translate.
Contributes information about words and other language-related entities to the Linked Data Web and Semantic Web, leading to a Web of Data in which the British Library, the Spanish National Library, and others have linked their data to, and in turn connects its own data to other valuable resources.
Datasets and resources for sentiment analysis and fine-grained emotion analysis, in part available for multiple languages.
AI Service Center
The AI Service Center Berlin-Brandenburg conducts research on how to best provide AI cloud and consultancy services to third-party organizations. Funded by BMBF.
Etymological Wordnet
A database of etymological and derivational relationships between words in different languages, mined from Wiktionary.
Source Code
We have published the source code for a number of different research projects. Follow the link for a list of available code bases.
