ICF International has developed a Microsoft Excel-based tool known as the BMDS Wizard that allows a user to run multiple sessions consecutively in the U.S. Environmental Protection Agency's (EPA) Benchmark Dose Modeling Software (BMDS) and stores all inputs, outputs, and decisions made in the modeling process. All benchmark-dose modeling is conducted using EPA's BMDS software; the BMDS Wizard acts as a "shell" surrounding BMDS. The BMDS Wizard simplifies the BMD modeling process by streamlining data entry and option file development, implementing logic to help compare and evaluate models, and automating the documentation in a report format. It is capable of analyzing continuous, dichotomous, and dichotomous-cancer datasets. The Wizard stores all inputs and output from BMDS, including output files and image files in the Microsoft Excel workbook.
The BMDS Wizard recommends best-fitting models using decision logic that can be customized by the user. A user may choose to agree or disagree with the recommendations made by the BMDS Wizard. Once a user selects a best-fitting model, the BMDS Wizard automatically generates a Microsoft Word summary report. Model recommendation criteria are based primarily on EPA's 2012 Benchmark Dose Technical Guidance1, although additional tests have been added. The BMDS Wizard is also designed to integrate with the DRAGON software, which contains much of the dose-response data used in a comprehensive risk assessment.
Current Release: Version 1.7 (updated February 2013)

Joshua Cleland has 20 years of experience providing technical support for U.S. federal environmental quality and food safety regulatory programs. His areas of expertise include chemical exposure and risk assessment, environmental modeling, and federal laws and regulations pertaining to solid and hazardous waste management, air and water pollution control, food safety, organic foods, and biotechnology.
Mr. Cleland has used Microsoft Access and Visual Basic for Applications to create more than 30 user-friendly information management and decision support tools and models for the U.S. Environmental Protection Agency (EPA), Food and Drug Administration (FDA), Department of Agriculture (USDA), Federal Aviation Administration (FAA), and other clients. For example, he built a risk-ranking model for FDA to evaluate chemicals in imported aquaculture products, a tool for USDA to aggregate salmonella monitoring data from poultry production facilities, and a tool for FAA to estimate atmospheric emissions from commercial space flight programs. For EPA, he developed the Multimedia Ingestion Risk Calculator (MIRC), a model to estimate human health risk from chemical exposures through diet and other noninhalation exposure pathways.
Mr. Cleland holds a master’s degree in Natural Resource Economics and Policy from Duke University and a bachelor’s degree in Biology from the University of Michigan.
