My research seeks to enhance our understanding of the interface between hydrological processes and vegetated ecosystem functioning, as this is critical to the advancement of natural resource & watershed management. I primarily perform field-based investigations of forest ecohydrological processes, focused in 3 areas:

(1) Biogeochemical dynamics of dissolved organic matter and ionic nutrients from plant canopies,

(2) Effects of storm-related hydrologic processes on plant and soil ecology, and

(3) Instrumentation/methods development for researching interactions between canopies and canopy fauna.

Although my main research site is located in coastal Georgia (USA), I have also collaborated with scientists in Switzerland, Germany, Panama, Iran, Maryland, Colorado and Washington State to investigate the interactions between forests and their environment. These experiences provide unique data sets for inclusion in classroom activities and opportunities for engaging students in collaborative, international research. When not researching or teaching, you can usually find me jogging and kayaking with my wife, Stefanie, and sons, Beck & Levi.

Current research projects
  • Influence of epiphyte vegetation and microbial communities on precipitation water and nutrient cycling by plant canopies.
  • Alteration of ecohydrological processes by urbanization and urban greening.
  • Connections between plant canopy rainfall partitioning and soil physicochemistry and microbial communities.
