International Epidemiology Institute

The International Epidemiology Institute (IEI) was a prominent private research organization specializing in the design, execution, and analysis of complex epidemiologic studies. Established in 1994 by former senior scientists from the National Cancer Institute, the institute provided high-level scientific consulting and research services to government entities, the private sector, and legal counsel. IEI's expertise spanned various domains, including cancer etiology, occupational and environmental health, and the safety of medical products and devices. The organization was recognized for its rigorous scientific methodology and its role in significant public health research, such as the Southern Community Cohort Study. In 2013, IEI was acquired by Westat, where its staff and expertise were integrated into Westat's health research practice.
