Research

I am `universitair hoofd docent' (associate professor) in the research group Analysis and Dynamical Systems, financed by a VIDI-grant by the Dutch Science Organisation NWO.
My research interests are in dynamical systems and partial differential equations.


PhD students



VIDI-grant

In 2006, I was awarded a VIDI-grant by the Dutch Science Organisation NWO.
This grant is titled `Formation of singularities in natural systems' and started on 1 January 2007.
A summary and more information of the research can be found here.
