Me, hiding behind one of my dogs.

For my work in mathematics I am kindly hosted by Utrecht University, The Netherlands. My PhD advisors are O. Diekmann and S.A. van Gils. I also cooperate with Yu.A. Kuznetsov.

My interest is in functional analytic methods for dynamical systems. At the moment I investigate well-posedness and dynamics of various classes of delay equations via dual semigroup theory.

I am motivated by problems from mathematical biology, control theory and approximation. Problems from different domains often have an underlying structure in common.

Delay equations is also the eponym of a domain that I have registered for the plan of creating a cooperative wiki about aspects of theory and examples of delay equations. If you would like to cooperate, let me know.
