I am interested in stochastic processes on graphs, and in random graphs. Particular fields and applications of my research include: Network centrality (quantify the relevance of a node in a network), in particular PageRank in undirected vs. directed networks;Existence, uniqueness and extremality of infinite-volume equilibrium states (Gibbs measures) in statistical mechanics, in particular in low-temperature regimes;Loss, recovery and preservation of regularity properties of stochastic processes under transformations, in particular renormalization group pathologies.
