Currently I'm a postdoc in Probability Theory at Tsukuba University, where I am supported by JSPS as an International Research Fellow. I am hosted by David Croydon (Kyoto University) and Ryoki Fukushima (Tsukuba University).
Previously
I have written my PhD thesis about "random polymers in disastrous environments" with Nina Gantert at TU Munich. Between November 2019 and October 2020 I was a postdoc at RIMS, Kyoto University.
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 resistane forms.
