my position

I have my PhD in theoretical physics. Have been a postdoc in math and mathematical physics for four years at Hamburg University. Was based for a bit at MPI in Bonn and am now on a postdoc position in Ieke Moerdijk’s group in Utrecht.

my research

My research has to a large extent been motivated by thinking about mathematical model building in theoretical physics. With co-editors we are currently producing a book that should give a good sense of modern insights into the general abstract structure of the world:

This is the kind of stuff that I am thinking about.
