Chemical Biology and Exposure Science

A helix with images of various environmental exposures.

Understand the fate and function of chemicals in humans and microbiomes by focusing on environmental, dietary, industrial, and warfighting exposures

Our research team investigates the fate and function of chemicals linked to exposures from diet, industry, Earth’s environment, and—with increasing urgency—warfighting.

Our experimentalists and modelers collaborate as experts in toxicology, exposure science, modeling, epidemiology, and risk assessment.

They have core technical capabilities in analysis, toxicology, biomonitoring, computational modeling, whole-animal imaging, internal dosimetry, and nuclear magnetic resonance.

Our research team comprises a broad range of capabilities: exposure science, nanotoxicology, multi-scale virtual models of the respiratory system (for dosimetry prediction), radiation biology, structural biology, biomarkers, nondestructive imaging, spectroscopy, and magnetic nanoparticle detection.
