Research Interests

Ionization and characterization of acidic compounds by negative ion electrospray (ESI) mass spectrometry with emphasis on:
  • Effect of solvent and solution conditions on negative ion ESI response
  • Prediction of negative ion ESI response
  • Characterization of acidic compounds in complex environmental and agricultural samples

Research Description

Dr. Christine A. Hughey is an analytical chemist whose research centers on method development for the characterization, quantification and study of acidic polar compounds in complex environmental and agricultural samples by negative ion electrospray ionization mass spectrometry (ESI MS).   The interdisciplinary nature of her research affords her the opportunity to work on a variety of projects from the characterization of flavonoids in antioxidant-rich food extracts to field studies that investigate the use of naphthenic acids as molecular indicators of in-situ bioremediation in crude oil-contaminated soil.  These applied projects have led her to pursue studies that investigate the fundamental mechanisms involved in negative ion ESI, which are not well understood.  Specifically, she is interested how solvent and solution conditions effect the ionization of acidic compounds.  Improved understanding of ESI ionization mechanisms will lead to development of a predictive model of negative ion ESI response.
