Networks, networks everywhere
ˇ Network infrastructure, social networking
ˇ Network  a tool for understanding complex systems
ˇ Many nonidentical elements connected by diverse interactions
ˇ Cellular interaction networks: signal transduction, gene
regulation, metabolism
ˇ Graph measures provide information on interaction graphs
ˇ Network models explain and predict properties of graph classes
ˇ Network topology influences network robustness and the
dynamics of flows
ˇ Dynamics of cellular networks
ˇ Understand emergent properties synchronization, phase
transitions, homeostasis
