This research focuses on the measurement science of per- and polyfluoroalkyl substances (PFAS) in the environment, food, and human health materials. As emerging contaminants, there is a significant need for the development of state-of-the-art analytical methods, reference materials, and data tools to help stakeholders better detect chemical signatures, identify novel PFAS, and quantify targeted PFAS in a wide range of matrices. Instrumentation available for this research include gas chromatographs, liquid chromatographs, high resolution mass spectrometers (QTOF and Orbitrap), ion mobility paired mass spectrometry, triple quadrupole mass spectrometers, and nuclear magnetic resonance (NMR) spectrometers. Research interests include (but are not limited to): (1) development of novel methods for the identification and/or quantification of PFAS in complex matrices, (2) creation of novel materials or material processing protocols for the quality control of PFAS measurements in complex matrices, and (3) generation of reference data to enable better identification of unknown PFAS.
