Assistant Professor
Biography

My research is motivated by two general questions: 1) how does weather variability, landscape heterogeneity, and human manipulation of landscapes control the magnitude of water fluxes in the terrestrial water cycle, and 2) how do the same factors control to distribution of water travel times through landscapes?  My research includes field-based observational studies, laboratory- and field-based manipulative experimentation, and application of various flow- and transport-modeling techniques.  I also utilize stable-isotopes of water as hydrological tracers, and operate a laser spectrometer in my laboratory for analysis of stable-isotope ratios in water samples.

Areas of Expertise:

Catchment Hydrology

Vadose Zone and Ground Water Hydrology

Urban Hydrology

Applications of Stable Isotope Tracers in Hydrology
