Predict population health risks linked to microbial pathogens
Food (fresh and processed)
Modified organisms (contamination, cleanup)
Estimate magnitude of disease burdens
Identify high risk sub-populations
Dialysis, cancer patients
Guide policy decisions
Ordered, iterative process
Complete source-response pathway assessments
Use field & clinical measurements
Accommodate different pathogens, contexts, scenarios, dynamics
Assumptions, data limitations
Open, transparent processes
What is THE problem?
How can it be modeled?
For what purpose?
Comprehensiveness of approach
Analytic plan (sources & use of data)
Linkages of dynamic ecological & population scale disease models
Compatibility of model structure & components with complexity of the problem
Evaluation of the model
Analysis of uncertainty & variability
Explicit identification of assumptions
Use of probabilistic methods
