Offical roles

Studerandeombud

I am one of two studerandeombud ("student ombudsman") at Chalmers. If you need to contact me in this role, please visit the official web page.

Director of studies

I am one of two director of studies for the Division of Computing Science at CSE.

Previous roles

I was viceprefekt (vice head of department) for undergraduate education 2014–2019.

Research

I share my time between two departments: Computer Science and Engineering, and Språkbanken Text at the Department of Swedish, Multilingualism, and Language Technology.

Interests

My main interest is language technology, i.e., how to get computers to understand human language. At the moment I am mainly pursuing two paths – grammar formalisms and quantitative text analysis. My interest in grammar formalisms is very general and can be summarised in the following question: "How we can use grammars to specify and encode not just linguistic syntax, but also other information?". My interest in text analysis is how it can be used for understanding socio-linguistic phenomena.

Projects

Currently I am involved in the research projects Korpsearch, Språkliga nätverk, and MoCCA. Previously I have been involved in the research projects Analysis of gender bias, Hot och hat mot journalister, MUSTE, NLTK, REMU, GRASP, Lekbot, SubTTS/Pratmakaren, FraCaSBank, MOLTO, DICO, TRIK, TALK, TRINDI, and INDI.

Publications

The University of Gothenburg has a list of my publications, including some unpublished work and presentations, most of them downloadable.

Software

All open-source software I have been working on the past years can be found on Github.
