Mary Bedner ()

Mary first came to NIST while a graduate student at the University of Maryland, where she worked on the characterization of organic disinfection byproducts formed during wastewater treatment with chlorine. She expanded this work during her post-doctoral appointment, where she explored the reactions of pharmaceutical compounds during wastewater treatment to better understand their environmental fate. This work was highlighted in both an A-page news article in Environmental Science and Technology and as a news story on a local television station. After her post-doc, Mary remained at NIST and has worked on a number of SRM projects including vitamin D and creatinine in human serum, bioactive constituents in dietary supplement materials, and standards for explosives. The primary focus of her work is LC method development, which she uses with a number of detection techniques including mass spectrometry, electrochemistry, and ultraviolet-visible absorbance. She has also participated in several international comparison studies to determine the purity of organic compounds using a variety of LC techniques. Mary is currently the program coordinator for the Clinical Quality Assurance Program (ClinQAP) and its subprogram, the Vitamin D Metabolites Quality Assurance Program (VitDQAP).

Mary is currently on detail as a Scientific Advisor in the Material Measurement Laboratory office to support the development of strategies for environmental assessment, climate mitigation, and water.
