Willem van Zuijlen

I am a postdoc at the Weierstrass Institute in Berlin, in the research group Interacting Random Systems.

My main scientific interests lie in the treatment of models from stochastic analysis and statistical mechanics. I am working on topics like spectra of random operators, behaviour of singular stochastic partial differential equations, self-repellent random walks in random media, dynamical Gibbs-non-Gibbs transitions, and derive rigorous results about their asymptotic behaviour by using technical tools from analysis.

I am taking care of the SPP2265 Website. For updates please contact me via spp2265 (at) wias-berlin.de.
