During the 2011/2012 academic year I am a postdoc with Eli Berger.
My field of research is Combinatorics, in particular Graph Theory. I am working on topological aspects of infinite graphs and their ends (see here for an introduction). I am also interested in infinite matroids, cooperative colorings, and independent systems of representatives.
