Invited Plenary Talk:
Biological Systems as Reactive Systems

Speaker: Luca Cardelli

Systems Biology is a new discipline aiming to understand the behavior of
biological systems as it results from the (non-trivial, "emergent")
interaction of biological  components. We discuss some biological
networks that are characterized by simple components, but by complex
interactions. The components are separately described in stochastic
pi-calculus, which is a "programming language" that should scale up
description of large systems. The components are then wired together,
and their interactions are studied by stochastic simulation. Subtle and
unexpected behavior emerges even from simple circuits, and yet stable
behavior emerges too, giving some hints about what may be critical and
what may be irrelevant in the organization of biological networks.
