Biography

 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 chemisty, oceanic emissions of halocarbons to the atmosphere, insturment 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. Currently, I am developing a mass spectrometer 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 persuit of these research goals, several instruments are currently being developed: a quadrupole based noble gas mass spectrometer, and new GC AED system to quantify groundwater age tracers.
