I am absent for indefinite time due to illness. For any mathematics business, just contact Frank Redig.


I did my PhD at the VU Amsterdam. My supervisors were Ronald Meester and Frank Redig. From 2008 to 2010 I was Assistant Professor at the University of Technology in Delft. I have been postdoc at CWI and at the VU Amsterdam. I have also been a teacher and an experimental physicist; click here for a full cv.
I won a NWO Meervoud grant, and am back at the TU Delft as assistant professor since May 2011! My contact details are:

Research interests

Self-organized criticality in sandpile models, limiting shapes in sandpile growth models (see here for some large size examples by David Wilson on the square, honeycomb and triangular lattice), bootstrap percolation, cellular automata. In the movie below you see a sandpile growth model that might not have a limiting shape (open problem in this paper by Haiyan Liu and me)
