Senior Scientists

Dr. Seeley is a senior toxicologist with experience in the areas of human health risk assessment, exposure assessment, litigation support, and regulatory comment. Dr. Seeley performs critical reviews of animal toxicology and human epidemiology studies, conducts multipathway human health risk assessments, develops toxicity criteria and health-based exposure levels, and evaluates exposures for non-standard exposure scenarios. Before joining Gradient, Dr. Seeley worked as an NIEHS Research Fellow at the University of Washington, where she studied the health effects of air pollution. Dr. Seeley has authored or co-authored peer-reviewed articles and book chapters on a variety of topics, including risk assessment, health effects of perchlorate and nitrogen dioxide, endocrine disruptors, and developmental toxicity. She has also served on two committees of the National Academies’ Institute of Medicine. 

Toxicity Evaluation of Airport-Related Hazardous Air Pollutants: Evaluated information regarding the toxicity of airport-related hazardous pollutants to establish priorities for a research agenda for the National Academies' Transportation Research Board.

Risk Assessment of PCBs in Caulking Material: Characterized historical exposure and risk to workers exposed to PCBs in caulking material.

Toxicity of Pyrethroids: Assessed the toxicity of pyrethroids and potential health effects associated with their use for airline disinsection.

Safety Assessment for Medical Implant: Performed toxicological evaluation of oil residues on medical implants. Assessed the potential for long-term health effects.

Toxicological and Risk Evaluation of Perchlorate: Conducted in-depth evaluation of animal toxicological studies in terms of human relevance. Coordinated human volunteer study involving low-level perchlorate exposure.

Pesticide Risks New York City: Estimated the potential public health risks associated with spraying pesticides for control of mosquitoes bearing the West Nile Virus, and assisted in preparation of the Environmental Impact Statement.
