• Teaching
• Students
• I have advised vertically integrated graduate-undergraduate research projects at MEGL, most recently “Predicting Flood Zones Using Topological Data Analysis”.

Research

My current research is primarily in the fields of dynamical systems and mathematical visualization and design. Recent research includes

• Study of quasiperiodicity and chaos
• Computational methods for studying dynamics
• Rigorous computation of bifurcations
• Phase field models in materials science
• 3D printing of mathematical objects

For more details, see my Publications and Talks.
