Epidemiologist Analyst

This gives Claude an epidemiological framework for analyzing disease patterns, outbreak investigations, and public health interventions. It comes loaded with theoretical foundations from germ theory to causal inference, including Bradford Hill criteria for distinguishing correlation from causation. You'd reach for this when evaluating vaccination programs, investigating foodborne illness clusters, modeling disease spread, or assessing health disparities. The skill emphasizes population-level thinking over individual cases and quantitative precision through rates and risk ratios. It's thorough on the conceptual side with references to John Snow and the Framingham studies, though you'll still need to provide your own data and context for specific analyses.
