I am a post-doctoral researcher in SFB 732 Incremental Specification in Context. My project is titled D2: Combining Contextual Information Sources for Disambiguation in Parsing and Choice in Generation. My research interests include parsing Turkish, and parsing non-canonical text and domain adaptation, and Turkish-German code-switching.


Before joining the IMS, I worked at the CNGL, Dublin City University, on improving the automatically labelling of English data with deep syntactic information based on Lexical Functional Grammar (LFG). I got my Ph.D from Sabanci University, Turkey. My thesis was on building a large scale grammar for Turkish within the LFG framework. I was also involved in building the Turkish Wordnet.
