Research

My fields of interest are Veech groups of translation surfaces and Teichmüller curves in moduli spaces. I have particularly worked on special cases that arise from coverings of elliptic curves that are ramified over at most one point, called square tiled surfaces or origamis.
This work lead me to the study of subgroups of mapping class groups, of subgroups of the automorphism group Aut(F_n), Out(F_n) and GL(n,Z) and the Culler-Vogtmann outer space. I am especially interested in relations between Teichmüller spaces and outer spaces.


Since summer 2007: Research project With origamis to Teichmüller curves in moduli space. More informations about our research on origamis in Karlsruhe can be found here: Origamis in Karlsruhe

Since Summer 2009: Research project Culler and Vogtmann's outer space and Out(F_n) - geometric and algorithmic approaches (within the program RiSC by the KIT and the State of Baden-Württemberg)
