Title: Senior Exposure Scientist; Research Environmental Engineer; Community Public Health Project Lead

EPA Division: Human Exposure and Atmospheric Sciences Division

EPA Branch: Exposure Modeling Research Branch

Valerie’s research focuses on developing, applying, and providing human exposure science, models, and decision support tools to inform EPA and community/tribal decisions for improving environmental health. Projects include:

  • Stochastic Human Exposure and Dose Simulation model for multimedia chemicals (SHEDS-Multimedia; http://www.epa.gov/heasd/products/sheds_multimedia/sheds_mm.html), which supports EPA risk assessments and regulatory decisions regarding residential pesticides and other toxic substances;
  • C-FERST (http://www.epa.gov/heasd/c-ferst) and Tribal-FERST(http://www.epa.gov/research/healthscience/health-tferst.htm), environmental decision support Web-based tools for building sustainable, healthy communities and tribes;
  • Health Impact Assessment (HIA) to evaluate proposed remediation scenarios for indoor sources and near-roadway transportation exposures for an EJ community school in Springfield, MA; one of EPA’s first HIAs and first school building-focused HIA in the field;
  • local scale exposure modeling to advance the science and understanding of cumulative risk from multiple environmental stressors to communities and individuals;
  • exposure factors to reduce uncertainty in human exposure and risk assessment; and
  • collaborative efforts and case studies to harmonize human exposure assessment approaches internationally.
