   intro_statements:
   - I am a volcanologist with a specialization in volcanic gases. Such gases are
     ultimately what drive volcanism and can give precursory signals in advance of
     eruptions. My research involves studying the amounts, behavior, and chemistry
     of those gases, with a goal of improving our understanding of their role in
     volcanic activity.

   personal_statement: "Over the course of my career as a volcanologist, I have worked\
     \ on a wide range of projects. But the common factor between all of them is\
     \ volcanic volatiles, otherwise known as volcanic gases. My research goal has\
     \ always been to better understand how those volcanic gases behave in volcanic\
     \ systems, before, during, and after eruption. This has meant that I\u2019ve\
     \ gotten to study how volcanic gas plumes interact with topography and vegetation\
     \ in Nicaragua; the chemistry of tiny amounts of volatiles trapped within rocks\
     \ erupted tens of thousands of years ago in Alaska; connections between escaping\
     \ gas, seismicity, and explosive eruptions in Guatemala; and even how different\
     \ volatiles dissolve in magma when you create your own tiny, high-temperature\
     \ molten rock in a laboratory.Here at the Hawaiian Volcano Observatory, my focus\
     \ is still volcanic gases. HVO routinely monitors gas emissions from K\u012B\
     lauea and Mauna Loa volcanoes using a range of permanent measurement stations\
     \ and portable instrumentation. In addition to monitoring, I conduct research\
     \ on gas chemistry using MultiGAS sensors, FTIR spectroscopy, and direct sampling.\
     \ For research on gas emission rates, I use UV spectrometers and UV cameras.\
     \ Recently, I have also been involved in new initiatives at HVO to use UAS (unoccupied\
     \ aircraft systems) to measure gas chemistry, emission rates, and sample volcanic\
     \ plumes, as well as to sample the short-lived water lake at K\u012Blauea summit.\
     \ I also use measurements of volatiles still dissolved in rock and mineral samples\
     \ to supplement my work on gas emissions.I spent a number of years as an educator\
     \ before arriving at HVO and very much value science education, especially for\
     \ young students. So, in addition to my research and monitoring efforts at HVO,\
     \ I participate in a number of outreach activities with students of all ages."
