Me, hiding behind my dog.

My name is Sebastiaan Janssens and I work in mathematics under supervision of my PhD advisors O. Diekmann and S.A. van Gils and also in cooperation with Yu.A. Kuznetsov at Utrecht University and the University of Twente in The Netherlands.

My interest is in mathematical analysis and infinite-dimensional dynamical systems. Currently I study well-posedness and dynamics of various classes of (partial) delay equations via dual semigroup theory. See my publications.

My motivation comes from within mathematics as well as from mathematical biology and, more recently, systems and 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 have expertise and would like to cooperate, consider letting me know.
