News

• 2018-11: Inga Kempfert presented our paper about an error tagger for German at the NLP4CALL workshop. The results are from her bachelor's thesis.
• 2016-12: For my last presentations, I created a Latex Beamer template based on the corporate design of Universität Hamburg. You can find the unofficial template here.
• 2016-10: Timo and I hosted a group in the trial study week (Schnupperstudium) on Spoken Dialogue Systems from October 17th to 21st and we were voted best project! Here's the video. While having fun with dialogues, we got to know fundamental computer science concepts such as variables, recursion, grammars and data structures.

Research Interests

• Grammatical error diagnosis (and correction)
• Processing/Parsing language learner data
• Integrating contextual information into parsing
• Hybrid Parsing

Other Interests

• Doing stuff with Org mode

Useful stuff

• I highly recommend everyone who has to correct and rate students' assignments submitted by email to have a look at abgaben.el for emacs and mu4e. This setup speeds up the process immensely.
