• I am a post-doctoral fellow in the Natural Language Processing (NLP) group here at EML Research gGmbH. I find all aspects of language fascinating, and hope to get a better understanding of linguistic phenomena and their relation to cognitive processes through the study of words -- both as forms (how they emerged and how they change) and as meaning -- in isolation and in complex contexts. These days I work on structuring and extracting knowledge from the multi-lingual Wikipedia, exploiting this knowledge for high-end applications such as summarization,  and exploring ways of structuring evidence from language use for the representation of word meanings.
