Marcel Bollmann

Associate Professor

Computational linguist and researcher in natural language processing (NLP).

Natural language processing and machine learning

I am associate professor at the division Artificial Intelligence and Integrated Computer Systems (AIICS) at the Department of Computer and Information Science (IDA).

I am a computational linguist and researcher in natural language processing (NLP). My research interests revolve around NLP and machine learning in challenging scenarios, such as under-resourced languages, multilinguality, or historical documents. I am particularly interested in linguistically-informed approaches to NLP, as well as bringing improvements in NLP technology to a wider range of languages and text genres.

CV in brief


  • I have obtained my PhD degree (Dr. phil.) in Computational Linguistics at Ruhr-Universität Bochum, Germany, in 2018.
  • My research was funded by various projects related to historical language corpora of German, and my dissertation is on the normalization of historical language data.


  • Between 2018 and 2021, I was a postdoc in the CoAStaL NLP group at University of Copenhagen, Denmark.
  • During that time, I received funding from the EU in form of a Marie SkÅ‚odowska-Curie Fellowship (MSCA) for a project on “morphologically-informed representations for NLP.”
  • Our paper on “Error Analysis and the Role of Morphology” won a “Best Long Paper” award at the EACL 2021 conference.

Assistant professor

  • Between 2021 and 2023, I was assistant professor at the Jönköping AI Lab (JAIL) at Jönköping University, Sweden.
  • I contributed to the advanced-level study program in “AI Engineering”, creating new courses on “Data Science Programming” and “Natural Language Processing.”


  • As a volunteer, I also contribute to the development of the ACL Anthology as Site Development Lead.
