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.

Since joining Risk Sciences International in 2019, Martin has served in Business Development, leading RSI’s business expansion efforts across Canadian and global markets. He is instrumental in identifying and qualifying opportunities, coordinating multidisciplinary proposal teams, developing project frameworks, and supporting contract negotiations. His expertise spans the entire procurement spectrum, including competitive tenders, standing offers, supply arrangements, and unsolicited proposals.

Hong Duan is a Systems Analyst and Application Developer at Risk Sciences International, where she has applied her expertise since 2011. She holds a Bachelor of Computer Science degree from the University of Ottawa and is certified as a Microsoft .NET Professional Developer. Hong specializes in developing database-driven, risk-based web applications.

As an Associate Expert with Risk Sciences International, Dr. Arnold brings clinical depth and field experience to RSI’s work in occupational health risk assessment and workplace safety policy development. He provides expert insight on topics such as exposure-related health outcomes, physical and psychological stressors in industrial settings, and the integration of clinical data into population-level risk models.

Dr. Willhite is an Associate Expert at Risk Sciences International, where he supports the development of quantitative health risk assessments for both naturally occurring and synthetic chemicals. His work draws on decades of experience integrating toxicological evidence, regulatory frameworks, and structure–activity data to inform science-based decision-making. His expertise adds significant value to RSI’s assessments of chemical tolerability, exposure limits, and public health protection standards.

As a Microbiologist with Risk Sciences International, Dr. Sattar contributes his deep expertise in pathogen ecology, environmental microbiology, and infection control technologies to support RSI’s work in health risk assessment and risk mitigation. His insights guide RSI’s contributions to evidence-based disinfection strategies, microbial exposure modelling, and policy-relevant evaluations of infectious disease risk across water, air, food, and surface-contact pathways.

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.

Dr. Anne Wiles joined Risk Sciences International (RSI) in 2008, where she currently serves as a Senior Analyst specializing in risk communication, perception, and governance. With a distinctive blend of expertise in language, regulation, and the use of science in decision-making, Anne has contributed to a wide range of RSI projects focused on the human and institutional dimensions of risk. Her work includes developing health risk communication strategies and drafting publicly accessible scientific information, advising on public messaging for nuclear energy and nuclear waste management, and supporting regulatory agencies in the evaluation and management of complex risk portfolios. She has been deeply involved in several RSI projects examining how mandates, institutional contexts, and public attitudes shape regulatory decision-making across federal domains. Anne has also contributed to scholarly work at RSI, including co-authoring a scoping review on the evolution of health and environmental risk decision-making, an article on the potential health risks associated with aluminum, and a book chapter on public concerns related to blood safety. In addition to her project work, Anne is a university instructor, teaching two courses: a broad overview of societal approaches to risk, and a graduate seminar on risk management in government, where she integrates academic theory with real-world regulatory case studies and risk communication practice.

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.

Dr. Larkin serves as an Associate Expert at Risk Sciences International, specializing in policy, regulatory analysis, and population health risk assessment. Her work with RSI has included life cycle assessments of metals, as well as a review of Alberta’s Water Cytotoxicity Testing Program. She contributes rigorous, equity-sensitive approaches to risk analysis, and brings a nuanced understanding of the intersections between policy, science, and public values.
