     personal_statement: I joined the Denver Argon Geochronology Laboratory at the

      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.
