square_blue.pngAbout me

I am responsable for the outreach programme of the Institute of Mathematics at the University of Innsbruck. We have several outreach events for schools and pupils such as: Tag der MIP, Girls' Day, Mathe auf Abruf, Mathe-Cool, Naboj. For more information, visit our outreach webpage, or send an email to

I am currently associate professor in mathematics at the University of Innsbruck (Austria), Department of Mathematics. Before that I was tenure track assistant professor at the same department, and prior to that I was assistant professor (non tenure-track) at Graz University of Technology (Austria) and a visiting assistant professor at Cornell University, USA. I have obtained the Habilitation (venia docendi) in Mathematics at TU Graz (Austria) in February 2020, at the same university where I have received my PhD in December 2010, under the supervision of Wolfgang Woess.

Research grant Growth models and quasi-random walks, Austrian Science Foundation (FWF). Project number P 34129. Project members: Yuwen Wang (postdoc, previously Cornell University, USA), and Robin Kaiser (PhD student).


square_blue.pngResearch Interests

In a broad sense, I am interested in understanding how complex patterns emerge from simple local rules. My research deals mostly with the interplay between structural and geometrical properties of infinite graphs and the behavior of random walks and of rotor walks (derandomized versions of random walks) on these graphs. I am investigating the differences and similarities of these two walks (random and rotor walk) in relation to the underlying graph structure, which may be random or not.
I am also working on internal aggregation models (IDLA, rotor-router aggregation, sandpile models) on fractal graphs and other state spaces. Moreover, I also have some interests in zig-zag products of graphs, (geometric) boundaries of random walks, abelian sandpile Markov chains. For more details, just look at my publications.


square_blue.pngBachelor and Master Thesis

I am currently supervising Bachelor and Master Theses in the area of stochastics and combinatorics at the University of Innsbruck. A list with possible topics is available below. This topics may give you an idea in which direction I do research. Concrete topics can be given only after a personal discussion.
