Title: Kazdhan's theorem on metric graphs

Abstract: I will give an introduction to the concept of a canonical (Arakelov) metric on a metric graph, which is related to combinatorial questions like the counting of spanning trees, and generalizes the corresponding concept on Riemann surfaces. I will also present a recent result with Farbod Shokrieh on convergence of canonical metric under normal covers.
