I am a PostDoc

  • 50% at Radboud Universiteit Nijmegen in the LinC project. Here I work on statistical analysis of typological, areas and genetic relationships among South American Indian languages.
  • 50% at the Max Planck Institute for Evolutionary Anthropology Dept. of Linguistics. Here I work on infrastructure for linguistic typology, genetic and areal relations among African languages, linguistic diversity and Papuan languages. In particular, I am starting to document Mor [moq] on the Bomberai peninsula, Papua, Indonesia (an endangered language isolate).

Previously, I did my PhD (2009) at the Department of Computing Science and Engineering at Chalmers University, Gothenburg, Sweden. I was then working in Language Technology, more specifically on the problem of Unsupervised Learning of Morphology.

Since 1996 and forever more I am a Python Programmer.

I am co-organising History, contact and classification of Papuan languages2-3 Feb 2012. Deadline for submission of abstracts 15 Aug, 2011. Don't Miss!

The agenda for the LinC group can be found here.
