   abstract: I am a research chemist studying methods of groundwater age determination.
     I am generally interested in the relationships between atmospheric gases and
     groundwater, as mediated by the interactions in the vadose zone, the layer of
     the ground that water must pass through before it enters an aquifer.I have a
     background in experimental atmospheric chemistry, having worked with several
     groups on topics including ocean fertilization, biogeochemical impacts to atmospheric
     chemistry, oceanic emissions of halocarbons to the atmosphere, instrument validation
     studies, long term observations, anthropogenic emissions, and air quality measurements.Dissolved
     Gases are important chemical tracers in groundwater systems. They provide information
     about groundwater age, aquifer mixing, and the climate conditions when water
     entered the aquifer. This information can be used to study issue of groundwater
     availability, quality, and quantity. Additionally direct measurements of these
     properties can be used to validate groundwater model output and improve model
     algorithms, allowing more accurate assessment of aquifer systems. I have designed,
     constructed several noble gas mass spectrometer and GC systems to measure dissolved
     fixed gases (O2, N2, He, Ne, Ar, Kr, and Xe) to assess groundwater recharge
     temperatures more accurately, and I am studying the behavior of various anthropogenic
     compounds in the groundwater system.In pursuit of these research goals, I have
     developed novel and customized analytical systems and sensors for research and
     production operations. Among others, these include an automated economical quadruple
     mass spectrometer based noble gas analyzer, a dual channel GC-FID-AED system
     for measuring trace hydrofluorocarbons (as novel groundwater age tracers) and
     trace hydrocarbons (to better understand hydrocarbon geochemistry, a highly
     automated multi-port noble gas analyzer for tritium-helium dating and noble
     gas concentrations in groundwater, a self contained low cost pCO2 sensor, and
     GC-TCD system for measurements of He/Ne in groundwater samples.
