Dr. Nason uses liquid chromatography coupled with high resolution mass spectrometry (LC-HRMS) to detect contaminants in agricultural and environmental systems. She is interested in understanding how organic contaminants move and transform in the environment and how environmental releases of chemicals can lead to unintended human exposures and health impacts.


Current Research

Dr. Nason’s current projects include:

  • Examining contaminant movement and transformation in agricultural systems that use recycled wastewater for irrigation

  • Testing the effectiveness of remediation efforts for sites contaminated with per- and polyfluoroalkyl substances (PFAS)

  • Developing reliable and reproducible methods for suspect screening and non-targeted analysis studies using LC-HRMS

Past Research

Dr. Nason’s graduate work focused on mechanisms for plant accumulation of polar and ionizable organic contaminants. As a postdoctoral fellow, she focused on learning LC-HRMS techniques and examining contaminant transformation pathways in waste treatment systems.
