## Research Interests and Papers

My research interests include areas in both pure and applied mathematics. Recently, I have focused almost exclusively on applied topics, studying applications of network theory and modeling to problems in economics, neuroscience, sociology, political science, and psychology. My work in pure mathematics focuses on the study of the solutions of geometric partial differential equations in sub-Riemannian (or Carnot-Caratheodory) geometries.
