Research and Teaching Interests

I am a hydrologist, with a geological training, whose research goal is to further understand how physical hydrologic processes influence water quality and movement through watersheds. I am particularly interested in understanding how water moves through paired surface water and groundwater systems, heat tracing in hydrologic systems, and interactions between the energy and water cycles.

My broad interest in the exchange of water between surface and subsurface environments has led me to do several specific interdisciplinary research projects. Generally, my research involves field experiments coupled with computer modeling experiments.

Watershed Hydrology Lab: The Watershed Hydrology lab contains instrumentation for laboratory analysis of the chemistry of natural waters and for collecting field measurements. The lab is well equipped with several refrigerators for sample storage, fume hoods, drying ovens, mass balances, adjustable pipettes, and volumetric glassware.

Major laboratory instrumentation includes:
- Two-Column Dionex Reagent Free Ion Chromatography System, ICS-2000, with autosampler (for simultaneously measuring anion and     cation concentrations, such as calcium, magnesium, chloride, sulfate, and nitrate, among others)
- Picarro L2130-i Water Isotope Analyzer, with autosampler (for measuring oxygen and hydrogen isotopic composition of water)
- Barnstead NANApure DIamond Ultrapure Water System (for water deionization)

Field instrumentation includes:
- Nikon Reflectorless Total Station (and accessories)
- Portable WTW pH/specific conductance/dissolved oxygen probes
- Geopump Persitaltic Pumps and an FMI piston pump for well sampling
- Flow-through field fluorometer
- ADV velocity meter
- Marsh-McBirney flow meters
- iButton temperature data logger
- Davis VantagePro2 weather stations
