Dynamical systems, mathematical ecology
Motivated by problems of environmental change, I am interested in how dynamic structures persist or change in the face of disturbances and uncertainty. I look beyond a dynamical system’s invariant sets to study the interaction between transient behaviors and disturbances. These questions tie to applications ranging from the effect of glacial meltwater on oceanic circulation to the effect of nutrient pollution and management on grassland community structure. Answers to date have integrated a variety of topics, including nonautonomous control, Conley theory, and multivalued dynamics.
