Currently Since August 2021, I am an Assistant Professor at the Mathematical Science
Group of AIMR (Advanced Institute for
Materials Research) at Tohoku University, Japan. The main
focus of my research is probability theory, specifically its applications to problems from mathematical
physics and material science.
Previously
Between November 2019 and June 2021, I was a postdoc hosted by David Croydon and Ryoki Fukushima at RIMS, Kyoto University, and at Tsukuba University. I was supported by the
JSPS Postdoctoral Fellowship for Research in Japan (Standard Programm).
I have written my PhD thesis supervised by Nina Gantert at TU Munich.
See here for a short CV.
Research interests I mainly work on the following topics:
 The directed polymer model and first/last passage percolation.
 (Branching) random walks in random environment.
 Stochastic orders, in particular for the above processes.
 Oriented percolation.
 The random conductance model, and the Mott random walk in particular.
More broadly, I'm interested in the following areas:
 Statistical mechanics.
 Random matrices and integrable probability.
 Large deviation theory.
 Random walks on graphs and their resistance forms.
