研究テーマ
The main focus of my research is probability theory, specifically its applications to problems from mathematical physics and material science:
- The directed polymer model and first/last passage percolation.
- (Branching) random walks in random environment.
- Oriented percolation.
- The random conductance model, and the Mott random walk in particular.
