RISK SCIENCES, LLP specializes in sound scientific analyses and tools to support risk-based decision-making related to human health and the environment. Our multi-disciplinary expertise includes exposure, risk, and decision analysis, as well as model development and risk communication. We have applied these skills to community-based, occupational, and public policy assessments.
Dr. Katherine von Stackelberg, Principal, specializes in developing risk-based tools and methods to support sustainable approaches to environmental decision-making. She holds a non-teaching research affiliation at the Harvard Center for Risk Analysis, part of the Harvard School of Public Health, where she is Leader of the Superfund Research Translation Core. In that capacity, she is responsible for developing outreach strategies and materials across diverse stakeholders to communicate the public health and policy implications of basic research. Much of her work has focused on incorporating quantitative uncertainty analysis (e.g., analytical, probabilistic, and fuzzy methods) into the environmental management process, and she has been at the forefront of the effort to explore methods for effectively communicating and interpreting uncertainty in scientific analyses to support environmental decision-making. Dr. von Stackelberg has managed and served as technical lead for several large US EPA and US Army Corps of Engineers projects focused on contaminated sediments. She is an experienced modeler, and served as technical lead for the development of several aquatic food web models used to support risk-based decision making for the Corps and US EPA, including FishRand and TrophicTrace. Dr. von Stackelberg is an advocate of decision analytic approaches for supporting decision-making by integrating environmental models, stakeholder preferences, and GIS-based data and modeling. She is involved in developing approaches to quantify changes in ecosystem services, and identifying relationships between ecosystem services and expected benefits with the goal of integrating economics and risk assessment to better quantify the benefits of proposed risk reductions as a result of management or regulatory actions for use in cost-benefit, cost-effectiveness, and value of information analyses.
Dr. von Stackelberg serves as peer reviewer for numerous journals, and is on the editorial boards of Human and Ecological Risk Assessment and Risk Analysis. She is the Chair of the global Science Committee for the Society for Environmental Toxicology and Chemistry (SETAC), and the outgoing Chair of the North America Science Committee. She serves as Treasurer for the Society for Risk Analysis. She is a member of the Scientific Advisors on Risk Assessment for the European Commission in Brussels. Dr. von Stackelberg received an A.B. cum laude from Harvard College, and a Sc.M. and Sc.D. from the Harvard School of Public Health in Environmental Science and Risk Management.
Dr. Pamela Williams, Principal, has expertise in exposure assessment, retrospective exposure analysis, human health risk assessment, decision analysis, and risk communication. She is also currently a Clinical Assistant Professor in the Department of Environmental and Occupational Health at the University of Colorado, and a Fellow with the non-profit organization, Toxicology Excellence for Risk Assessment. She has extensive scientific consulting experience and has served as a Senior Science and Policy Advisor in the Office of Research and Development at the U.S. Environmental Protection Agency. Her work has included conducting scientific literature reviews and analyses of various chemicals in the environment, characterizing human exposures and health risks in occupational and community settings, designing and implementing indoor air exchange rate and exposure simulation studies, and designing environmental health education materials. Most of this work has been published in the peer-reviewed literature and presented at technical and scientific conferences nationally and internationally.
Dr. Williams serves as a peer reviewer for numerous journals, peer review panels, and government agencies. She is on the editorial board of Human and Ecological Risk Assessment. She is current Chair of the Risk Assessment Committee of the American Industrial Hygiene Association and past Chair of the Exposure Assessment Specialty Group of the Society for Risk Analysis. She also previously served on the Board of Directors of the Society for Risk Analysis. Dr. Williams is the 2007 recipient of the Joan M. Daisey Outstanding Young Scientist Award, granted by the International Society of Exposure Science in recognition of outstanding contribution to the science of human exposure analysis by a young scientist, and is the 2009 recipient of the Chauncey Starr Distinguished Award, granted by the Society for Risk Analysis in recognition of excellent contributions to the field of Risk Analysis. She received a Fellow Award from SRA in 2012, granted in recognition of substantial achievement in science or public policy related to risk analysis and substantial service to the Society. Dr. Williams received her Master of Science (MS) degree in Health and Social Behavior and her Doctor of Science (ScD) degree in Environmental Science and Risk Management, both from the Harvard School of Public Health.
