Biography

Guillaume Guex

I am from Lausanne, Switzerland and I made a Bachelor in applied mathematics in the EPFL (Swiss Federal Institute of Technology in Lausanne), a Master in statistics (University of Neuchâtel) and a PhD in Geography (University of Lausanne). My research is about graphs, shortest-path, random-walks, optimization and algorithms. During my PhD i worked on the model « randomized least cost flow » . It is a model of flow in a graph, with a tuning parameter allowing to interpolated between least cost flow and random flow. It was used to solve various problems, in particular the optimal transportation problem on a graph.
