Fachgebiet

I'm working on the field of nonlinear dynamics. I'm mainly interested in bifurcation theory, particularly for piecewise smooth sytems, in border collision and homoclinic bifurcations, in low-dimensional chaos and bifurcations of chaotic attractors (crises). My further research interests include numerics, simulation software and algorithms, as well as neural networks.
