Dr. Rula Deeb is a senior principal civil and environmental engineer at Geosyntec Consultants in Oakland, California, where she leads Geosyntec's PFAS program and serves on the Board of Directors. She has more than 25 years of experience in private practice and academia addressing the cross-media fate and transport of contaminants and the remediation of complex soil and groundwater sites. Her focus on emerging contaminants over the last two decades has promoted awareness and improved the understanding of the sources, occurrence, fate and transport, and behavior of these compounds (including PFAS and 1,4-dioxane) in natural and treatment environments. She has actively advocated for advancing the state of knowledge on PFAS over the last 10 years by organizing webinars and conferences with a strong PFAS focus including The Remediation Summit (RemTEC) and the Emerging Contaminants Summit. She recently served as a member of the planning committee for a 2019 National Academies of Sciences, Engineering, and Medicine workshop entitled "Identifying Opportunities to Understand, Control, and Prevent Exposure to PFAS." In 2019, she was inducted into the Civil and Environmental Engineering Academy of Distinguished Alumni at the University of California, Berkeley.
