Dr. Paul Price is a Senior Analyst at Risk Sciences International (RSI), bringing over four decades of experience as a pioneer in exposure science and chemical risk assessment. Since joining RSI in 2019, Dr. Price has focused on advancing mixture risk assessment—an increasingly vital area as regulators shift from assessing single chemicals in isolation to understanding the cumulative effects of combined exposures. His current work includes the development of Mixture Adjustment Factors, participation in international regulatory committees, and authorship of scholarly publications aimed at refining the science-policy interface of chemical mixture risk.

Effective modeling and predictive analytics are essential for anticipating risks, evaluating interventions, and informing operational, financial, and policy decisions under uncertainty. Strong models enhance planning, resilience, resource optimization, resulting in strategic and financial value to the organization and strategic credibility.

The International Aluminium Institute (IAI) recently commissioned Climate Risk Institute (CRI) and Risk Sciences International (RSI) to produce a series of informational tools evaluating and explaining the future effects of climate change on the aluminium sector’s sustainability. A principle focus of the project was to highlight one of the most consequential effects of climate change,…

RSI facilitates recovery planning that integrates risk reduction, community priorities, and systemic reform. Its cross-sector expertise supports holistic approaches—from critical infrastructure to psychosocial recovery. RSI ensures that pathways are feasible, inclusive, and adaptive to the uncertain pace and character of post-crisis recovery.

RSI is well positioned to integrate NAMs into its Understanding Risk methods by aligning scientific innovation with policy realism. RSI’s teams include toxicologists, modelers, and risk analysts with experience in interpreting NAM outputs within weight-of-evidence frameworks. The firm can evaluate the appropriateness of a given NAM for a client’s specific context, help interpret model results, and document methodological decisions in a transparent and policy-ready manner. RSI’s ability to translate novel science into applied insights ensures that NAMs are used effectively and credibly in support of regulatory and advisory functions.

RSI’s Dr. Emma Hartnett chaired the recent Joint FAO/WHO Expert Meeting on Microbiological Risk Assessment (JEMRA). The focus of the week-long event held March 11 to 15, 2019, was the update and consolidation of technical guidance documents to allow for a more current and coordinated approach to assessing microbiological hazards in food.
