About
Catherine Rudisill, MS, PMP
Founder & Principal
In her role as a multi-disciplinary chemical assessor, Cathy utilizes innovative methods like in silico modeling, read across, and non-animal approaches to evaluate chemical alternatives with limited data. She actively promotes the use of functional and safer alternatives, integrating the principles of chemical alternatives assessment and informed substitution into her professional practice. Cathy’s work with government and outreach agencies underscores her commitment to incorporating safer chemical strategies into public and corporate policies. Since 2023, she has instructed the “Assessment Tools for Safer Chemical Decisions” for the University of Washington’s Green Chemistry and Chemical Stewardship Online Certificate program.
In her prior role at SRC’s globally-recognized Environmental Health Analysis group, she worked with clients such as the U.S. EPA, National Library of Medicine, Washington Department of Ecology, and global corporations like Nike. She worked with the U.S. EPA Safer Choice Program, one of the most impactful eco-labels on the market. She supported various Safer Choice initiatives, notably the publication and expansion of the Safer Chemical Ingredients List.
Cathy holds a BS in Chemistry from Shippensburg University and an MS in Environmental Sciences and Policy from Johns Hopkins University. She also earned a Certification in Sustainable Capitalism and ESG from Berkeley Law. Additional training includes expertise in assessing endocrine-disrupting chemicals. Recognized as a certified Project Management Professional (PMP) by the Project Management Institute (PMI).
She has co-authored several publications, chaired conference sessions, and is credited with more than 20 conference presentations since 2011. Her research centers around the assessment and promotion of alternatives to chemicals, with a strong emphasis on chemicals management policies, substitution of hazardous substances, and the use of alternative assessment methods. She is an active member of the Association for the Advancement of Alternatives Assessment (A4) Executive Council and a long-time member of the Society of Environmental Toxicology & Chemistry (SETAC) and the American Chemical Society (ACS).
