My main interests are in phylogenetic theory (parsimony analysis, character weighting, inapplicable characters, sequence alignment) and in plant systematics and evolution.
For my research in phylogenetics, I am associated with Göteborgs Botaniska Trädgård, the botanical garden of Gothenburg, Sweden. My day time job, as an ICT professional, is at the university of Leuven, Belgium. More information at LinkedIn.
More information about anagallis, my program for parsimony analysis of character hierarchies, can be found here. Quick download links are here.
I also contribute to Kevin Nixon's plantsystematics.org. To get an impression of the diversity in my garden and in the village I live in, wild as well as cultivated, you can enter Veltem-Beisem as a search term in the 'keyword or locality' field there.
