A branching random walk with self repulsion
We consider a discrete time branching random walk where each particle splits into two at integer times and the offspring move independently by a normal random variable. We introduce a penalty that penalises particles that get within a distance epsilon of each other. We analyse the most likely configurations of particles under the tilted measure for a fixed time horizon N. It turns out that spread very quickly to a distance 2^{2N/3} and show a very abrupt change in behaviour at time 2N/3. This is joint work with Lisa Hartung, Frank den Hollander and Stefan Müller.

Geodesic flow on CAT(-1) and (some) CAT(0) spaces
How do we define geodesic flow on a metric space? Which of the nice dynamical properties of geodesic flow on negatively or nonpositively curved Riemannian manifolds can we prove for their metric space analogues: CAT(-1) and CAT(0) spaces? In this talk I'll discuss some results on the geodesic flow for CAT(-1) spaces obtained jointly with Jean-Francois Lafont and Dan Thompson. Then I will report on some recent work with Ben Call, Alena Erchenko, Noelle Sawyer, and Grace Work on geodesic flow for flat surfaces with large-angle cone point singularities. These spaces include translation surfaces, and provide a first step in the direction of extending our results to the CAT(0) setting.
