square_blue.pngAbout me

I am currently a tenure-track assistant professor in mathematics at the University of Innsbruck (Austria), Department of Mathematics. 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.

square_blue.pngNEW: FWF Research Grant 2020-2024

In October 2020, my research proposal Growth models and quasi-random walks has been granted by the Austrian Science Foundation (FWF). Total amount 359.362 €, Project number P 34129. In Fall 2021, the project will start with one PhD and one postdoc.

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.
