Dr. Raga Avanasi is an interdisciplinary scientist with over a decade of experience in exposure science, regulatory strategy, and applied research across the domains of pesticides, environmental health, and chemical safety. He holds a B.Tech in Biotechnology, an M.S. in Environmental Toxicology, and a Ph.D. in Exposure Science and Risk Assessment. Dr. Avanasi’s academic, industry, and consulting work has centered on the human health risk assessment of chemicals for product safety and regulatory acceptance, grounded in technical expertise spanning exposure science, toxicology, risk assessment, and environmental epidemiology. Previously, at Syngenta Crop Protection LLC, he led the human safety strategy for a portfolio of active ingredients under U.S. EPA (FIFRA) and Canadian PMRA regulatory frameworks, overseeing dietary, residential, and occupational exposure assessments and higher-tier model refinements to support registrations and re-evaluations. He has directed several innovative projects advancing pesticide risk assessment, including integration of biomonitoring data with modeled exposures, higher-tier residential exposure model development, and seed treatment worker exposure mitigation. Dr. Avanasi also brings extensive experience in PFAS exposure reconstruction, uncertainty analysis, toxicology, and environmental epidemiology through his research with the C8 Health Project population. Additional areas of expertise include human health risk assessment of VOCs from oil and gas operations, systematic reviews of environmental health literature, nanomaterial fate and exposure analysis, and consumer product exposure modeling. He has published dozens of abstracts and peer-reviewed papers on various topics including exposure modeling, risk assessment, regulatory policy, and environmental epidemiology. Across academic, industry, and government collaborations, Dr. Avanasi’s work bridges scientific rigor with regulatory impact—delivering data-driven insights that inform chemical safety decisions and protect public health.

“I strongly believe in balancing risks and benefits to serve the greater good—a principle that guides my professional work in advancing science-based, health-protective decisions.”
