I am interested in all aspects of polyhedral, tropical and algorithmic geometry, and this includes topics such as optimization and combinatorial topology. See here for an overview of ongoing and past projects. In addition I like to design and apply mathematical software, the main project being polymake.

I am currently serving as Deputy Director of our institute.

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.


  • polymake 4.2 released [18 Sep 2020]; new interface from Julia: Polymake.jl 0.5.0 [28 Aug 2020]
  • Oscar 0.3.0 released [27 Apr 2020]
  • Forthcoming book "Essentials of Tropical Combinatorics". Take a look at the web page with an updated draft [27 Sep 2020] and send comments.
