Scientific Interests and Goals:
I have developed my research in the fields of Marine Ecology and Biological Oceanography. My most recent work has focused on the sources, accumulation, transport and diagenetic characteristics of the organic matter and carbon in continental margins and submarine canyons. Using biogeochemical models I estimated the sedimentary biogeochemical fluxes of the organic matter and bioturbation in these environments. I also studied the relationship between biogeochemical parameters (Corg, Chl a, NO3, NH4, O2, etc.) and the distribution of deep sea meiofauna and nematodes. In the past, I studied the effects of toxic algae blooms on meiofauna communities in seagrass beds. Furthermore, I worked on the effects of sediment dredging on meiofauna and sediment biogeochemistry (NO3, NH4,PO4, Corg, TN, etc.), and the recovery of the altered environment. Now, I am interested in studying the interrelationship between the biogeochemical processes in the marine environment and the ecology/biology of the biota. At present my research will focus on the effects of global warming and non-indigenous species on sea grass beds biogeochemical processes in the Mediterranean, and how the altered sediment biogeochemistry can affect the sea grass communities.
