IDEAS: Mathematical Models of Infectious Diseases (2017)


Program: 1st Annual IDEAS Workshop: Mathematical Models of Infectious Diseases
Location: University of Georgia
Date: May 17-19, 2017
Instructors: Pejman Rohani ( & John M. Drake (
Class objectives: This module covers the principles of dynamic models of infectious diseases. The module will focus on the dynamics of compartmental models such as the susceptible-infected-recovered (SIR) model and variants (SI,SIRS, and SEIR). Topics include incorporating different types of heterogeneities in transmission (resulting from age-structure, behavior or, seasonality), exact stochastic birth-death models, sensitivity analysis, and fitting of simple models to data. The module will alternate between lectures and computer labs. Programming will be done in R.
