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 broadly in functional analytic methods for infinite-dimensional dynamical systems. Currently I study well-posedness and dynamics of various classes of abstract delay equations via dual semigroup theory. See my publications.

My motivation comes from within mathematics and from questions in mathematical biology and – more recently – control theory.

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.
