Elin Ulrich

Title: Research Chemist

EPA Division: Human Exposure and Atmospheric Sciences Division

EPA Branch: Methods Development and Applications Branch

Elin’s research has focused on method development of analytical techniques (extraction, cleanup, and instrumental analysis) for the analysis of current use chiral residential pesticides, specifically the pyrethroid family. Her current research is focused on identification of biomarkers, developing methods for analysis, applying methods to biological samples, and interpreting the resulting biomarker data to understand exposure.
