Henning Ulfarsson

I am an Associate Professor in the Department of Computer Science at Reykjavik University. My research is in combinatorics, with a focus on permutation patterns and the algorithms that aid in studying them. I co-lead the Permutation Triangle research group. You can reach me at henningu@ru.is or browse my Google Scholar profile.
