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 animal toxicology data using the latest statistical methods and software, e.g. categorical regression, to establish safe exposure levels for acute and sub chronic effects.
• The estimation of benchmark doses (BMDs) from toxicology and epidemiologic data to develop the most statistically accurate points of departure for risk assessment.
• 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.
