Research
My research currently focusses on heat and diffusion equations in differential geometry. Curve Shortening is the simplest nontrivial example of such an equation (the video shows an example of a solution of Curve Shortening). Other examples include Mean Curvature Flow and Ricci Flow.
My other current research interest is in applications of mathematics to biology.
Teaching
