Short 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.
