## Contact Office H4017 Email: micbjo (you know what) chalmers.se I am an associate professor (docent) at Chalmers University, Gothenburg. My research is mostly concerned with the various interactions between ergodic theory, random walks, number theory and arithmetic combinatorics. ## Research interestsErgodic theory, arithmetic combinatorics (mostly approximate groups), geometry and dynamics on homogeneous spaces. ## Teaching at Chalmers and elsewhere Arithmetic Combinatorics. Lecture
