Hi, I’m Marek

I am a university professor at The Faculty of Mathematics, Informatics and Mechanics of the University of Warsaw. My main interests are continuous dynamical systems, namely ordinary and delay differential equations, equations with impulses, and sometimes reaction-diffusion equations. I am interested in constructing and analyzing models that describe biological or sociological processes. I study the qualitative properties of the solution of the models and try to relate the results to real situations.
