Dr. Franco Momoli joined Risk Sciences International (RSI) in 2019 and currently serves as Vice-President, Chemical and Product Safety. In this role, he leads a multidisciplinary team of epidemiologists, risk assessors, toxicologists, and biostatisticians in conducting human health risk assessments related to environmental contaminants and consumer products. His practice group supports government agencies, regulatory bodies, and international partners in making science-informed decisions that safeguard public health.

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.

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.

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.

Dr. Nataliya Karyakina is a Senior Toxicologist and Health Risk Analyst at Risk Sciences International (RSI), where she has served since 2008. She plays a central role in RSI’s work at the intersection of chemical safety, regulatory science, and human health. Drawing on more than three decades of experience, Dr. Karyakina contributes to complex projects involving the evaluation and assessment of hazardous properties of chemicals with different modes of action, hazard-based classification of chemical substances under CLP (EC) 1272/2008, and the development of health-based safety values for industrial and environmental chemicals for both workers and the general population.

Dr. Al-Zoughool has maintained a long-standing relationship with Risk Sciences International, both as a scientific collaborator and as a co-investigator on complex international projects. His work with RSI focuses on high-level public health risk modeling, mechanistic data analysis, and toxicological risk assessment of major environmental contaminants in air, soil, and water, including formaldehyde, lead, and 1,4-dioxane. His research also extends to methodological innovation and the development of evidence-based strategies for environmental and occupational health policy.

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.

Dr. Paul Stanish joined Risk Sciences International (RSI) in 2021 as a Risk Analyst, where he plays an essential role in advancing data-driven risk practices. Leveraging his strong background in chemistry and nanotechnology, he supports clients in building modern data cultures grounded in causal inference, machine learning operations (MLOps), and organizational performance measurement. His work ensures that risk frameworks not only incorporate emerging technologies but are also scalable and operational within institutional settings.
