As a Software Engineering Fellow at RSI, Dr. McNair brings unparalleled expertise in machine learning, Bayesian modeling, and decision-support systems. He supports RSI’s most advanced projects by designing and validating AI/ML architectures that meet both regulatory standards and ethical imperatives, including fairness, transparency, and distributive justice. His domain expertise spans from clinical prediction models to the risk analytics of high-reliability systems, with a particular focus on ensuring data quality and model interpretability.

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.

Margaret Wilson is a Senior Risk Analyst at Risk Sciences International (RSI), where she has been a foundational member since the company’s inception in 2006. Drawing on a rare combination of scientific breadth and analytical precision, Margaret has supported and led a wide range of multidisciplinary projects spanning microbial and chemical food safety, prion diseases, climate-related risk prioritization, and global regulatory systems.

Jennifer Go holds a BHSc in Health Sciences and an M.Sc. in Epidemiology, both from the University of Ottawa. Her academic work has spanned epigenetics, mental illness, and environmental exposures. Joining Risk Sciences International in 2017 as a Risk Analyst, she specializes in epidemiology. Jennifer's skill set includes systematic reviews, data manipulation, and statistical modeling. She has worked on diverse projects, ranging from pharmacoeconomic evaluations to analyses involving large datasets and electronic health records.

Daniel Krewski began his career in the federal government of Canada, focusing on programs within Health Canada, particularly in food safety and environmental health. Trained in mathematics, statistics, and biostatistics, his multidisciplinary background reflects the complex nature of risk science. He later transitioned to academia, founding the McLaughlin Centre for Population Health Risk Assessment at the University of Ottawa. There, he developed new methodologies and collaborated internationally. In 2006, he co-founded Risk Sciences International, aiming to provide expert advice on diverse risk issues. His contributions have been instrumental in shaping risk assessment frameworks used by organizations like Health Canada and the U.S. Environmental Protection Agency. In 2023, Dr. Krewski passed the CEO's baton to Greg Paoli; he remains active as RSI Chief Risk Scientist.

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.

Monique MacDonald is a seasoned Office Administrator with over thirty-five years of experience ensuring the smooth and efficient operation of office environments. She joined Risk Sciences International (RSI) in 2017, where she oversees the full range of internal operations and provides essential support across RSI’s scientific, operational, and client engagement activities. Her responsibilities include bookkeeping, financial support such as budgeting, invoicing, and expense tracking, as well as sales and marketing support. She also serves as operational and logistics coordinator for RSI’s convening events, including training sessions, workshops, and meetings.

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.

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.

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.
