square_blue.pngAbout me

I am currently a tenure-track assistant professor in mathematics and the head of the stochastics research group 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 got the Habilitation (venia docendi) in Mathematics at TU Graz in February 2020, at the same university where I have received my PhD in December 2010, under the supervision of Wolfgang Woess.

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. More details, just look at my publications.

square_blue.pngNEW: FWF Research Grant 2020

In October 2020, I've got a stand-alone research grant for my project Growth models and quasi-random walks, from the Austrian Science Foundation (FWF). Total amount 359.362 €, Project number P 34129. Starting with Fall 2021, I will have one PhD and one postdoc position available, each for three years.
