Past research projects

1991-1996 Master's degree at the ITFA, institute for theoretical physics of the university of Amsterdam. I specialized in statistical physics, writing my thesis on quasi-crystalline structure and random tiling models. The project was supervised by Bernard Nienhuis and Jan de Gier.
For a simple introduction to quasi crystals and random tiling models you might leaf through my thesis.
1997-2002 Ph.D. at the mathematical institute of Utrecht university and the Royal Dutch Meteorological Institute, KNMI, supervised by Ferdinand Verhulst and Theo Opsteegh. The results are summarised in my thesis, "Time scale interaction in low-order climate models".
I used bifurcation and continuation techniques to analyse low-order models of the atmosphere and the ocean. This resulted in a mix of modeling, scaling, Galerkin truncation, bifurcation analysis, singular perturbations and a considerable amount of trouble to relate all that to "reality".
Another paper (KMV), not included in my thesis, is the result of joint work with Yuri Kuznetsov and Hil Meijer on a certain codimension two bifurcation.
