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 primary area of research is environmental fluid dynamics, with an emphasis on physical-biological interactions in coastal environments. Current research activities include the effects of flow and turbulence on nutrient exchange in coral reefs, sediment transport in estuaries, chemical dispersion in the coastal ocean, and wave dynamics. My research also investigates coastal resilience. I explore how ecosystems such as coral reefs, seagrasses and oyster beds, both alter and respond to wave and storm impacts along coastlines.

I have research interests at a variety of scales, from microhabitat utilization of mice to biogeographic structures of entire island chains. Current research projects include: (1) the use of remotely sensed images and geographical information systems to produce chonosequences of insular vegetation, (2) testing of theories of socially induced dispersal, (3) biogeography of insular mammals, and (4) characteristics of image sources (satellites and aerial photographs) that affect perceptions of ecological landscapes.

My research group focuses on the dynamics of ecosystem change in shallow coastal systems, and the roles of climate, nutrient over-enrichment and species invasions on driving these changes. Current projects include: 1) Blue carbon sequestration in seagrass ecosystems, 2) Seagrass restoration and return of ecosystem services, 3) salt marsh resilience to sea-level rise, 4) ecosystem regime shifts in coastal barrier systems, and 5) impacts of invasive macro algae (Gracilaria).

I am an organismal ecologist with interests in both the ecosystem implications of physiological processes and the evolutionary underpinnings of these processes. My research centers around fundamental questions of resource acquisition and allocation in plants and touches upon such topics as herbivory and tri-trophic interactions, atmospheric chemistry and air pollution, community and ecosystem impacts of biological invasions, and organismal controls over element cycling.
