Daniel A. Vallero

Title: Research Physical Scientist

EPA Division: Human Exposure and Atmospheric Sciences Division

EPA Branch: Exposure Modeling Research Branch

Narrative:
Dr. Vallero is developing a system for prioritizing chemical ingredients based on their exposure potential. This includes both the inherent physicochemical properties as well as estimating the use and other human factors that may affect chemical exposures. His research also involves near-road exposures to toxic air pollutants.
