The general theme of the conference will be on the theory, modeling, and analysis of the temporal dynamics of biological populations. A special emphasis at this second conference will be placed on the modeling of epidemics. Mathematical modeling and analysis can be used to give insight and better understanding of the dynamics of biological populations. Mathematical models are built on trade-offs between biological accuracy and mathematical tractability. Of particular importance are the effects on a population's dynamics of modeling assumptions concerning spatial or temporal heterogeneities or concerning heterogeneities among the characteristics of individuals within the population and how these characteristics affect the way they interact with their environment. The invited speakers will address a wide variety of theoretical issues, applications (ecological, epidemiological, etc.), and case studies that illustrate the connection of models with data.
