Hey, I'm an editor at Nature Scientific Reports. You should go submit something!

NEW I'm co-organizing a workshop! 2014 KDD Workshop on Learning about Emergencies from Social Information (KDD-LESI 2014), Submission deadline June 24!

Research

Communities
Human mobility
Robust networks
Dynamics

My interests include: Complex Networks (community detection, social modeling and human dynamics, statistical phenomena, graph similarity and isomorphism), Statistical Physics (non-equilibrium methods, phase transitions, percolation, interacting particle systems, spin glasses), and Optimization (glassy techniques such as simulated/quantum annealing, (non-gradient) minimization of noisy objective functions), and more.
