## Areas of interest

I work in the general area of nonlinear differential equations, with particular interests in mathematical models for self-collective and swarming behavior. Such models can capture complex aggregation behaviours that emerge from simple interaction rules, in the absence of a leader or external coordination. I have worked on the mathematical analysis for various nonlocal aggregation models, and also on their applications to population biology, robotics and opinion formation. In previous research I studied regularizations of fluid dynamics equations, wave propagation in stratified media, and symplectic integrators for non-smooth Lagrangian mechanics.
