Research Interests
My research is primarily in the fields of dynamical systems and mathematical visualization and design. Current dynamical work focuses on studying systems with chaos and quasiperiodicity, and on developing rigorous computational methods for bifurcation theory. Visualization work concentrates on using 3D printing to create tangible objects from abstract mathematical concepts, and to design experimental objects to test mathematical models.
