Homepage of Christiaan J. F. van de Ven
I am a mathematical physicist interested in operator algebras, semiclassical analysis and their applications to statistical mechanics. Moreover, nonlinear dynamical systems and their various applications also pique my interest. I am currently an Alexander von Humboldt Postdoctoral Research Fellow working at the Department of Mathematics of the University of Würzburg in the Mathematical Physics group of Prof. Dr. Stefan Waldmann.
In December 2021 I obtained my PhD in Mathematics cum laude at the University of Trento under the supervision of Prof. Dr. Valter Moretti. To this end I was awarded a Marie SkłodowskaCurie PhD Fellowship part of the European project INdAMDPCofund2015 ‘INdAM Doctoral Programme in Mathematics and/or Application Cofunded by Marie SkłodowskaCurie Actions’ .
More information about me can be found in my curriculum vitae .
