Timo Seppäläinen

Timo Seppäläinen is Professor of Mathematics at the University of Wisconsin-Madison, specializing in probability theory and stochastic processes. His research examines random growth models, particle systems, and large deviation phenomena.

Key research areas include: 1) Kardar-Parisi-Zhang universality class and scaling limits; 2) Directed polymers and last-passage percolation; and 3) Fluctuation theory in spatially disordered systems. His work develops rigorous mathematical frameworks for complex random systems observed in statistical physics.

Recent publications analyze geodesic behavior in growth models, invariant measures in KPZ equations, and correlation structures in polymer models. Seppäläinen maintains collaborations across mathematics and physics to address fundamental questions in non-equilibrium statistical mechanics.
