My research interests lie in applying tools from linear algebra, matrix theory and dynamical systems to study graphs and complex systems. In particular, my work involves the Laplacian matrix and its eigenvalues, graph effective resistances and graph embeddings. In my latest project I am looking at discrete curvature on graphs, based on the effective resistance.
If you're interested in networks, be sure to check out the weekly Networks Seminar! Past talks are now also on Youtube.
