graph-tool — An efficient python module for manipulation and statistical analysis of graphs.

Research

My research focuses on characterizing, identifying and explaining large-scale patterns found in the structure and function of complex network systems — representing diverse phenomena with physical, biological, technological, or social origins — using principled approaches from statistical physics, nonlinear dynamics and Bayesian inference.

(If you are interested in inferring modular structures in networks using graph-tool, take a look at this HOWTO.)
