Topic: Noncyclic interactions: games within games

Cyclic predator prey games can create complex patterns in space and time such as domains and propagating spirals from simple microscopic rules. The coexistence of domains and spirals has been observed in a cyclic six species game where each species preys upon three others. This game is of particular interest as it exhibits the dynamical generation of multiple space and time scales. In this work we explore different interaction schemes to investigate the effects of these different scales on the patterns produced by the system and introduce a new non-cyclic game of nine species which produces spirals within spirals.

Topic: Whither noise? A discussion concerning the utility of stochastic modeling for cellular networks.

Biology is in the middle of a mathematical revolution, where quantitative models for complex biological systems are increasingly being used to detangle underlying molecular mechanisms. My presentation will first provide a general introduction for non-experts concerning the application of these mathematical models, and in short time, I will discuss the usefulness of stochastic (probabilistic) modeling for cellular systems. My claim is that nearly all single cell phenomena are noisy, but it is not immediately clear that the added workload required to pursue stochastic modeling ultimately pays off. I will provide supporting evidence (with caveats) in favor of this approach, which will serve as a launching pad for discussion.
