Biostatistics and Epidemiology

Biostatistical Methods

Motivated by a commitment to enhancing health, Westat biostatisticians skillfully employ suitable methods to tackle a diverse range of scientific inquiries in both observational and clinical research. Our analyses span from small patient samples in clinical settings to millions of records in electronic health systems, each potentially containing hundreds of data points. When existing methods fall short or the impact of an analytic decision is uncertain, we collaborate with our clients to develop and test new methodologies.

Epidemiologic Studies

Westat’s epidemiologists have been pivotal in critical epidemiological research, employing diverse study methods and designs to analyze data both retrospectively and prospectively. We’ve developed and utilized innovative tools and methods to support epidemiologic studies across a wide range of diseases. Our research has had direct public health and policy impacts.

Disease Surveillance

Westat leverages its expertise in epidemiology, statistics, and public health to enhance disease surveillance. By monitoring trends, identifying sentinel events, and tracking key metrics, we equip decisionmakers with vital situational awareness. Collaborating with federal and state agencies, we employ rigorous methodologies in both traditional and innovative data collection and analysis, delivering timely insights to drive public health action.
