-'''Abstract:''' Traditional differential equation models of chemical systems work well when the interacting chemical species are present in high concentrations. However, at the cellular scale, many processes in biology are driven by random collisions between molecules with small populations. These processes are inherently stochastic (random) and can display behavior that cannot be captured by deterministic models. In this talk, I will provide an overview of Gillespie's Stochastic Simulation Algorithm (SSA), a simulation method that captures this stochasticity. Unfortunately, the SSA is very computationally expensive. Since Gillespie’s pioneering work, many exact and approximate variations of the SSA have been developed to speed up these simulations. I will describe some of these algorithms and discuss their performance and scaling properties. Finally, I will present some of my recent work developing an efficient multiscale stochastic simulation algorithm.+''' Thursday, April 5, 2:30 in RNS 310'''

-'''Abstract:''' In 1951, John Nash showed that for any normal form game, there exists at least one strategy that is a best reply to itself. This strategy is known as the Nash Equilibrium and has multiple applications to various disciplines. We will introduce the concept of a Nash Equilibrium and consider how this idea may be applied to biology. In particular, we will discuss a game theoretic population dynamic called the replicator equation and show how the Nash Equilibrium corresponds to the stability of this system. Finally, we will consider applications of this model to populations of bacteria.+
