My primary research interests are in the areas of (1) catchment hydrology, focusing on hydrological and geochemical transport processes, and (2) land-atmosphere interaction, including the exchange of water, energy, and gaseous compounds such as carbon dioxide, nitrous oxide, and methane between the terrestrial surface and the atmosphere. I seek to develop an integrated understanding of how the hydrological cycle, vegetation processes, and atmospheric dynamics are linked as well as how these connections are manifest in terms of nutrient cycling and ecosystem function. My research combines a balance of field, remote sensing, and numerical modeling methods to address these issues over a broad range of spatial and temporal scales. Current field locations for my research include Shenandoah National Park, Ireland, and southern Africa.

TEACHING

Physical Hydrology (EVSC 3600)
Studies the physical principles governing the flow of water on and beneath the earth's surface, including fundamental concepts of fluid dynamics applied to the description of open channel hydraulics, ground water hydraulics, and dynamics of soil moisture. Introduces elements of surface water and ground water hydrology and explores humanity's influence on its hydrological environment.

Dryland Ecohydrology (EVSC 4020/7020)
Study of ecohydrologic processes characteristic of arid and semiarid regions.

Land-Atmosphere Interaction (EVSC 4630/7630)
Study of energy, water, and carbon exchange between the atmosphere and the land surface. Prerequisite: One year of college physics and calculus, one hydrology or atmospheric science course, or permission of instruct.

Hydrological Field Methods and Data Analysis (EVSC 4660)
Hydrological instruments are introduced; students employ the instruments to make field measurements and perform a range of data analysis exercises.

Catchment Hydrology: Process and Theory (EVSC 5640)
Introduces current theories of the hydrological response of catchments. Using an integrative approach, the course illuminates the derivation of theory in light of the time and location of the process studies on which they were based.
