Tetra Tech Sciences has considerable experience in the evaluation and conduct of epidemiologic studies. The staff participate in a number of professional epidemiologic and statistical societies and have contributed multiple journal articles, book chapters, and abstracts to the literature. Sciences staff are familiar with many of the popular statistical and epidemiologic data analysis packages. Some key project areas include:

• Design and conduct of epidemiologic studies.
• Review of epidemiologic studies for risk assessment.
• Quantitative estimation of risk at low level exposures from epidemiologic data.
• Sample size calculations.
• Biostatistics:
  • Biostatistics is the application of statistical analysis to the life sciences, including the analysis of epidemiology and toxicology data. It is critical in developing quantitative risk estimates from health-based data to estimate potencies of environmental agents for risk assessment. Sciences provides numerous public and private sector clients with expertise in biostatistics. Some of the key project areas in biostatistics include:
  • Analysis of epidemiologic studies, including meta-analysis of multiple studies and the application of epidemiologic data for risk assessment.
  • The use of biologically-based modeling to incorporate the mode-of-action into cancer risk assessments.
  • The application of advanced regression analysis in the analysis of environmental data.
  • TTS scientists regularly use STATA 10, Excel, and web-based applications for projects requiring statistical analysis.
