Current Research Contract: Johns Hopkins Evidence-Based Toxicology Collaboration
Technical research to identify more robust methodologies to ensure the science used to inform environmental and human health risk assessments is of high quality and provides the appropriate strength and weight of evidence necessary to base risk management and regulatory decisions on. Focus areas of this project include:
- Advancing the scientific approach used in the National Ambient Air Quality Standards (NAAQS) 5-year review process
- Further developing the science behind systematic review approaches in environmental health science
- Modernizing risk assessment practices by the creation of tools and approaches to apply Probabilistic Risk Assessment for criteria development and permit compliance
- Evaluating the data gaps between epidemiology and risk assessment
