TITLE: Models of Collective Behavior and the Opioid Epidemic

ABSTRACT: Over the last three years, my research has bifurcated into two distinct fields of study: one focusing on models and frameworks for the data-driven study of collective behavior in ecology and the other targeting addiction epidemiology, with a focus on prescription opioids in particular. In this talk, I will present some recent results from both of these areas as well as future directions. Starting with collective behavior, I will describe a two-pronged approach to modeling traveling wave fronts of locust swarms in 1-D utilizing both an agent-based model directly linked to individual behavior and a PDE model directly describing the collective, analytic behavior of the aggregate group. Results about the relationship between these models and conclusions drawn from biological data and parameter sensitivity analysis will be included. Next, I will describe a software framework under development for exploring emergent behavior in tiny organismal swarms living within complex, aqueous environments. Finally, I will switch gears and describe my work to date on models of the prescription opioid epidemic, including data-driven model projections for addiction in Tennessee and current work to extend analytic theory of infectious disease models to addiction models with linear addiction rates.
