Institut für Mathematik
Freie Universität Berlin
Arnimallee 2
14195 Berlin, Germany


I am a professor (W1Juniorprofessor) at Freie
Universität Berlin.
Before that I was a
Miller Research Fellow
at UC Berkeley.
Before that I graduated from Technische
Universität Berlin.
I am on the faculty of the Berlin Mathematical School
and part of the Junior faculty of the research
training group
Methods for Discrete
Structures. I am PI for the project A3 within the
CRC/Transregio
Discretization in Geometry and Dynamics.
My research interests are mainly in the areas of discrete and convex
(algebraic) geometry but
I am also interested (and worked) in
topological combinatorics and combinatorial commutative algebra.
Here is my CV.
Together with
Louis Theran and
Günter Ziegler I am
organizing the Discrete Geometry
Seminar.
If you think have something interesting to say, let me know.
Together with Matthias Beck I'm writing
a book on Combinatorial Reciprocity Theorems. Check it out!
Together with
Günter Ziegler and Michael Joswig, I am
organzing the workshop Delaunay
Geometry: Polytopes, Triangulations and Spheres.
It takes place October 79, 2013 here in Berlin.
