Research Interests

Dr. Kyle M. Samperton is a research scientist in the Chemical & Isotopic Signatures group within the Nuclear and Chemical Sciences Division at LLNL. With a background in geology and isotope geochemistry, Dr. Samperton is interested in applying mass spectrometric principles to study a diversity of subjects, from nuclear forensic science, radiochronometry, and related problems of national defense, to geochronology of magmatic processes and mass extinctions. These fields are united by a demand for sustained, ever-improving analytical excellence, and it is in striving toward this goal that he is excited to contribute to fulfilling the Lab’s mission of strengthening US security. He is also interested in the development of open source programming and statistical tools in support of enhanced data reduction, visualization, and interpretation. Prior to joining the LLNL staff in 2017, he earned degrees in geosciences at Princeton University (PhD, 2017) and the University of North Carolina at Chapel Hill (BS, 2010).
