Research Interests

Kyle Samperton studied geoscience at Princeton University and the University of North Carolina at Chapel Hill. After graduating with his PhD in 2017, Samperton joined LLNL as a research scientist in the Chemical & Isotopic Signatures group within the Nuclear and Chemical Sciences Division.

With a background in geology and isotope geochemistry, Samperton is interested in applying mass spectrometric principles to study a diversity of subjects from geochronology of magmatic processes and mass extinctions to nuclear forensic science, radiochronometry, and related problems of national defense. 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 and application of open source programming tools in support of enhanced data reduction, visualization, and interpretation.
