   personal_statement: "Gases are an important factor in volcanic hazards because\
     \ of their role in driving explosive eruptions and their intrinsic toxicity.\
     \  Part of the answer to, \u201CWhat could happen?\u201D at a restless volcano\
     \ comes from gas studies.  The mechanism of gas generation at depth and gas\
     \ migration up through boiling hydrothermal systems, cold groundwaters, and\
     \ the unsaturated zone are all complex processes that are only partly understood.\
     \  The goal of my research is to use gas flux, composition, and isotope values\
     \ to refine our general understanding of these processes and to apply this information\
     \ to studies that focus on the behavior and hazards of individual volcanoes.\
     \  The research involved identifying the areas of highest interest, planning\
     \ the field investigations, determining the most appropriate sampling protocol,\
     \ analyzing for the bulk composition and isotopic characteristics of the gas,\
     \ and interpreting and publishing the results."
