Catherine Rudisill, MS, PMP

Founder & Principal

Catherine Rudisill has 17 years experience providing expert research and consulting services. During her tenure 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 commercial organizations. In 2022, she founded her own environmental consulting firm dedicated solely to sustainable and safer chemicals.

For 10 years 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.

As a chemical assessor, her expertise focuses on the assessment of data poor chemicals by using in silico models, read across, and non-animal methods. Drawing from her experience with government and outreach agencies, she has been working towards the integration of safer chemical strategies into public and corporate policy.

Her multi-disciplinary background gives her a unique advantage in tackling complex sustainability issues. She has a BS in Chemistry from Shippensburg University, a MS In Environmental Sciences and Policy from Johns Hopkins University, Certification in Sustainable Capitalism and ESG from Berkely Law, plus additional training in the assessment of endocrine disrupting chemicals.

Cathy is a certified Project Management Professional (PMP) awarded by the Project Management Institute (PMI). This certification is awarded to professionals with extensive training and documented
experience in management best practices.

She has co-authored several publications, chaired conference sessions, and is credited to more than 20 conference presentations since 2011. She is an active member of the Association for the Advancement of Alternatives Assessment (A4) Executive Council, and is a long-time member of the Society of Environmental Toxicology & Chemistry (SETAC) and the American Chemical Society (ACS).
