Fernando Peruani

Research

I have broad interests in theoretical physics, technology and biology. As result of that, in my research, I attempt to use tools from theoretical physics to understand biological systems, and to find solutions to challenging technological problems. Depending on the specific problem, I develop theoretical models using elements from dynamical systems, non-equilibrium statistical mechanics, complex network theory, and/or stochastic processes. I always try to work in close collaboration with the experimentalists.

Active Matter

Characterization of self-propelled particle motion, transition to collective motion, clustering in self-propelled rods, and information spreading in system of self-propelled particles. Most of my research on active matter aimed at understanding myxobacteria collective motion and aggregation.

Complex Networks

Bipartite networks, robustness of finite complex networks, topological properties of Peer-to-Peer networks, and dynamical networks.
