Currently I'm a postdoc in Probability Theory at Kyoto 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.
Research interests I'm mainly working on the following topics:
More broadly, I'm interested in the following areas:
- 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.
- Statistical mechanics.
- Random matrices and integrable probability.
- Large deviation theory.
- Random walks on graphs and their resistane forms.
