Partial Differential Equations
I use a variety of computational tools (i.e., differential equations, agent-based modeling, and networks) to model social and biological phenomena. I have studied the development of name-brands and generics, the evolution of anisogamy (sex cells that differ in size), and the formation of multimodality for a generalized Kuramoto model (a standard model for synchrony). I am currently interested in trying take these tools and use them to study areas of inequity in society.
