Biological Networks
Large Networks

The remarkable progress in molecular biology has lead to a complete map of the building blocks of life. The next major challenge is to understand the interactions between the myriad of sub-cellular components that form the network structure of biological systems. My main research goal is studying and modeling these biological networks, and finding the fundamental principles that govern their topology, function and evolution.
