Hi all,
Please note this seminar. There are opportunities during the afternoon Monday to meet with Tim individually for anyone who might be interested. Please contact me if you would like to schedule a time.

*Behavior, Immunity, and Bistability in Simple Epidemiology Models *

*Monday February 14, 2011

Livak Room – 419 Davis Center*

In elementary models of endemic disease transmission, long-term dynamics can usually be summarized in terms of a single global attractor. However, a number of theoretical studies in the last decade have been shown that some epidemiological scenarios can have two or more locally stable equilibria, with population-dynamics that can potentially converge to either. This bistability may have important repercussions for public health policy and epidemic preparedness because it may lead to rapid and unexpected changes in disease prevalence. However, our understanding of the mechanisms creating bistability remains fuzzy. One potential cause of bistability is natural variation in the degree of individual resistance created by behavior changes and naturally acquired immunity. In this talk, I'll discuss some illustrative models of resistance to disease transmission. We'll see how different mechanisms of disease resistance lead to different population dynamics, and how over-simplified models can sometimes mislead us about general scenarios.

Dr. Reluga's research interests concern the description, understanding, and prediction of the dynamics of biological systems, and the implications of biology for human communities. This currently includes work in ecology, epidemiology, immunology, evolution, medicine, human behavior, and economics. Dr. Reluga completed his PhD in Applied Mathematics, "Results on Temporal and Spatial Heterogeneity in Theoretical Ecology" supervised by Prof. Mark Kot, University of Washington, Seattle, WA (June, 2004). He was a Research Fellow in Epidemiology and Public Health at Yale University (October, 2004 - May, 2006 ) in the Galvani laboratory, and a postdoctoral researcher at Los Alamos National Lab (September, 2006 - June, 2007) prior to accepting his current faculty position at Penn State.
