Colizza's main research activities focus on the characterization and modeling of the spread of emerging infectious diseases, by integrating methods of complex systems with statistical physics approaches, computational sciences, and geographic information systems. Current research explores the role of mobility on the worldwide propagation of human epidemics, strategies to control and mitigate pandemics, assessment of epidemic predictions provided in real-time (as e.g. for the 2009 H1N1 pandemic influenza), diffusion and security of cyber epidemics, livestock movements on animal disease spread, characterization and modeling of face-to-face human interactions and of multi-scale human mobility. Colizza also works on the development of the software GLEaMviz Simulator for the simulation of acute respiratory diseases at the global scale and on the online influenza surveillance systems, grippenet.fr and influweb, in France and in Italy, respectively.
