Research Interests
My research interests are in the tropical geometry of moduli spaces and its applications to classical questions in arithmetic and algebraic geometry. Given an algebraic geometric moduli problem, the basic idea is to first study the geometry of its tropical analogue, a polyhedral shadow of the original situation, and then to use techniques from nonArchimedean geometry and from logarithmic geometry to lift the insights gained this way back to the world of algebraic geometry. Here is a list of buzzwords that will surely spark my interest:
 Tropical and nonArchimedean geometry
 Logarithmic and toric geometry
 Moduli spaces and stacks
 Picard varieties and BrillNoether theory
Preprints
 Realizability of tropical canonical divisors (joint with Martin Möller and Annette Werner)
 Clutching and gluing in tropical and logarithmic geometry (joint with Alana Huszar and Steffen Marcus)
