Rachelle M. Duvall

Title: Research Physical Scientist

EPA Division: Human Exposure and Atmospheric Sciences Division

EPA Branch: Process Modeling Research Branch

Narrative:
Rachelle’s background is in the development and evaluation of receptor-based source apportionment models (CMB, PMF, and Unmix) and linking air pollution sources to health effects. Her current research focus includes: (1) the development and implementation of Federal Reference and Equivalent Methods (FRM/FEM) for criteria air pollutants, and (2) water-soluble organic carbon methods development.
