Epidemiologist
Uncover disease patterns, protect communities, and improve public health.
What is an Epidemiologist?
Epidemiologists investigate the causes and patterns of diseases and injuries in populations. They design and conduct studies, analyze data, and develop strategies to prevent and control health problems. Their work informs public health policies and interventions.
A typical day is coordination and analysis: monitoring surveillance reports, answering high-volume e-mail and phone calls, designing study protocols and sample selection, supervising data collection, running statistical analyses, and writing findings for clinicians or public-health leaders. Field visits and outbreak investigations occur episodically; most work happens indoors using precise methods to convert messy data into actionable recommendations.
