Kathie Dionisio

Title: Environmental Health Scientist

EPA Division: Human Exposure and Atmospheric Sciences Division

EPA Branch: Exposure Modeling Research Branch

Narrative:
The focus of Kathie’s current research activities is the improvement of alternative estimates of exposure for use in epidemiological studies, in an effort to fill in gaps in information which occur when central site monitor measurements are used as the exposure metric. Kathie also has an interest in global environmental health, particularly in the investigation of exposure from biomass fuels in the developing world, and the impact on child health.
