Clay Davis (Fed)

Research Chemist

Clay Davis is currently a Research Chemist in the Biochemical and Exposure Science Group at the National Institute of Standards and Technology (NIST) in Charleston, SC. He first started at NIST as a National Research Council (NRC) Postdoctoral Fellow to develop novel techniques to measure small molecule organometallic species and metalloproteins using atomic and molecular mass spectrometry.  Clay’s current work sits broadly within analytical chemistry applied to interesting biological questions utilizing the multi-omic applications of proteomics, metabolomics and lipidomics.  Current research projects focus on improving metrological quality and reproducibility including the optimization of sample preparation and data acquisition, quantification, and generating standardized multi-omic data sets to assess all steps of the measurement process. 

Clay is also heavily involved in developing resources for stakeholders including advancing and harmonizing measurement science via the production of reference materials with the principle goal of promoting best practices to produce high quality multi-omic data. Specific reference materials applications include clinical, non-model organisms, soil, and plant biota, as well as materials for understanding microbial systems.  NRC Postdoctoral Fellowships are available for U.S. citizens to apply to work with Clay at NIST Charleston.
