Title: Stochastic Models of HIV Infection
During infection, the HIV population is both attacked and attacks immune system cells. The result is a
coupled system of populations that presents many mathematical, statistical, and biological challenges.
In this talk, I will first review the deterministic dynamical system models of HIV infection that have been
developed over the past 20 years. As I will explain, while these models have greatly expanded our
knowledge of HIV, they have some inherent limitations in terms of biological application. I will then
discuss recent work involving stochastic models of HIV-immune system interaction. I will connect these
stochastic models and corresponding theoretical results to some open biological questions involving
