Position: Assistant Professor, Department of Oceanography and Coastal Sciences
Office: 2209 ECE Building
My research focuses on the processes that shape coastal environments. I am interested in coupling physical and biochemical aspects, e.g. ecogeomorphology and biogeology. I carry forward my research using mathematical models, laboratory experiments and field work. My current agenda encompasses three main topics: 1) Wetland response to sea level rise, sediment supply and storminess. 2) Coupled dynamics of sediment & biofilms / microbial-mats. 3) Carbonate platform sedimentary processes.
