I am interested in all aspects of polyhedral, tropical and algorithmic geometry, and this includes topics in optimization, combinatorial topology, applications to biology and more. See here for an overview of ongoing and past projects. Moreover, I like to design and apply mathematical software, the main projects being polymake and OSCAR.
Letters of Recommendation: I am willing to write letters for deserving candidates, but please read Frank Sottile's note on this subject before asking me for a letter. Frank's comments apply to you and me as well.
