Karen W. Phinney (Fed)

Karen Phinney joined NIST as an NRC postdoctoral fellow. Her early work at NIST focused on applications of supercritical fluid chromatography (SFC) and capillary electrophoresis (CE) to enantiomeric separations. She then became involved in development of analytical techniques for clinical and nutritional analytes, including vitamin D, and developed expertise in mass spectrometric methods. She has been responsible for the development of reference materials and reference methods for forensic, clinical, and nutritional markers and has led efforts to develop standards for proteomics and metabolomics. In her current role as group leader of the Bioanalytical Science Group, she is involved in the development of techniques for protein characterization and quantification, including therapeutic proteins and protein biomarkers. She received her Ph.D. in analytical chemistry from the University of Hawaii – Manoa and also received an M.S. in biotechnology from Johns Hopkins University.
