Coastal Geomorphology

I seek to develop a more integrated understanding of how coastal landscapes and ecosystems evolve together. My work take place across various research sites and environments, from temperate salt marshes in the United States to tropical mangrove forests in Southeast Asia. Our results highlight the importance of local ecological feedbacks in shaping how these ecosystems respond to environmental change, such as sediment dynamics and sea-level rise. My research also increasingly focuses on the resilience of coastal systems to extreme weather events. In partnership with federal agencies, we are examining how natural features like salt marshes and mangroves can buffer coastlines against hurricanes, storm surges, and erosion. These efforts support broader societal goals around coastal protection and climate adaptation, particularly in areas where large-scale restoration projects are underway.

Rising Waters

I am actively involved in interdisciplinary projects addressing the impacts of sea-level rise on coastal ecosystems. I examine how rising seas and storm events affect the transition zones between marshes, forests, and farmland. My work emphasizes the importance of preserving salt marshes, which play a crucial role in carbon sequestration, water purification, and protecting infrastructure from storm surges.

Vegetation promotes flow retardation and retention in deltaic wetlands

Coastal wetland vegetation slows and delays tides, extending water residence time and altering nutrient and sediment fluxes. By delaying ebb tides and raising minimum water levels, it lengthens hydroperiods, improving conditions for species in low areas. This feedback illustrates vegetation’s role in stabilizing deltas through self-organization
