Occupation
Epidemiologist
Epidemiologists study patterns of disease and health in populations and what explains them. The work is largely quantitative (study design, surveillance data, and statistical analysis), and it feeds directly into public health decisions. Outbreak roles can be intense and time-pressured; surveillance and research roles are steadier.
Also known as: Public health epidemiologist · Infectious disease analyst · Field epidemiologist
