Dr. Saad is a geochemist specializing in California regulatory science, including experience with the Department of Pesticide Regulation (DPR), Department of Food and Agriculture (CDFA), Department of Public Health (CDPH), and the Office of Environmental Health Hazard Assessment (OEHHA). Dr. Saad handles scientific issues within the context of unique state regulatory policies.
Dr. Saad has a strong scientific background in analytical chemistry and geochemistry. Her research has typically integrated both field- and laboratory-based projects. She has worked extensively on projects related to the presence and significance of nutrients and contaminants in soils and sediments, including transport, bioremediation, and environmental fate. She has also participated in investigations of contaminant provenance, not only identifying whether contamination in various ecosystems was anthropogenic or naturally occurring, but also constraining sources.
At Technology Sciences Group (TSG), Dr. Saad was a key scientist in their California (Davis) office. Dr. Saad worked on a broad range of issues, from chemistry and food safety issues to environmental fate and agricultural field trials. She has worked with clients on the many unique issues and challenges that arise out of California’s approaches to regulation and science. She brings an analytical and technical geochemistry background as well as a passion for navigating California’s environmental regulations to Exponent.
