     Geochronology Laboratory at the Geology, Geophysics, and Geochemistry Science
     Center.

   personal_statement: I joined the Denver Argon Geochronology Laboratory at the
     USGS Geology, Geophysics, and Geochemistry Science Center as a Mendenhall postdoctoral
     fellow in 2020. I was previously a postdoc in the Mid-Atlantic Noble Gas Research
     Laboratory at NASA Goddard Space Flight Center. I received my PhD from the School
     of Earth and Space Exploration at Arizona State University in 2017, and a BA
     in Geology and Physics from Middlebury College in 2011.My previous research
     mostly focused on high spatial resolution and incremental heating 40Ar/39Ar
     geochronology of lunar impact melt rocks. I also performed thermal-kinematic
     numerical modeling to assess Ar loss due to the formation of melt veins in polymict
     impact breccias, and I developed a software tool to promote more robust reuse
     of previously published K-Ar and 40Ar/39Ar datasets. My current research focuses
     on 40Ar/39Ar geochronology of igneous rocks and alteration minerals associated
     with a variety of critical mineral deposits in the U.S.
