Read More William Leiss
As a Senior Advisor and Associate Expert with Risk Sciences International, Dr. Leiss contributes unparalleled insight into the design, delivery, and evaluation of risk communication strategies for government, regulatory bodies, and civil society. His legacy work in building public trust around controversial science and his decades of thought leadership on consensus-building, science-based policy, and societal responses to risk make him a foundational contributor to RSI’s mission.
Read More Paul Price
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.

Read More Shintaro Hagiwara
Dr. Shintaro Hagiwara is a Risk Analyst and Statistician at Risk Sciences International (RSI), where he contributes cutting-edge statistical insight to risk assessments, particularly in chemical safety and public health. Since joining RSI’s technical team in 2018 and transitioning to a full-time role in 2023, he has applied his deep quantitative knowledge to building theoretical foundations and developing statistical software. Notably, he created the database-calibrated assessment process (DCAP) and the enhanced value-of-information (VOI) framework to aid in evidence-based regulatory decision-making, both of which have been reviewed by the Board of Scientific Counselors (BOSC). His applied statistical work provides assessments and tools to derive PODs for chemicals such as inorganic arsenic and fluoride to support both Canadian and international regulatory bodies.
