I am a senior lecturer and researcher at the University of Utrecht.
My
research interests are primarily in ergodic theory and its application
to
other fields such as number theory, probability theory and symbolic
dynamics.
See also my publications.
I am also interested in the area of financial mathematics and I have
been
the master thesis advisor of several students who wrote their thesis in
this
area.
