    Projects and Research Interests

    Natural Language Processing - Machine Learning - Digital Humanities 

    I have been part of the DMIR Research Group since I received my diploma degree in Mathematics in 2012 at the University of Würzburg. For the first two years I was mainly teaching, afterwards joining the Kallimachos* group to research genre distributions in German novels. In 2016/17 I was on maternal leave due to having twins. 

    At the moment I am working on transfer learning in the context of NLP to improve supervised tasks like semantic relation classification. I am interested in processing textual data to extend digital and human knowledge about language.
