Profile

Fabio has entered in the Oceanography graduate program at SOEST, University of Hawaii in the fall of 2006, sponsored by a CAPES-Fulbright scholarship.

He has obtained his Masters degree in Biological Oceanography by the Oceanographic Institute of University of Sao Paulo, Brazil in 2003. He has more than 10 years of experience working with marine benthic communities (macro and megabenthos) from coastal, shelf and slope areas, addressing environmental changes caused either by natural variability or by human activities, in particular coastal and offshore oil drilling/refining operations.

Now he focus his career on deep-sea environments, particularly submarine canyons, expecting to unravel some complex patterns of biodiversity and energy/matter flows inside these abrupt submarine topographies. His work has the potential to generate new information to support fisheries management and to aid in the design of Marine Protected Areas (MPAs) of biodiverity and biomass hotspots in the ocean.

As fieldwork experience Fabio has recently completed 365 days at sea in the last summer expedition of the FOODBANCS-2 project. He also has been in research cruises in Brazil, Hawaii, New Zealand and Antarctica, working with several oceanographic instruments such as sediment coring devices, dredging and trawling, CTD/Rosette casts, plankton nets, ROV'S, towed camera platforms, etc. Fabio has also been in a couple of submersible dives inside submarine canyons off Oahu and Molokai, Hawaii, as part of his PhD research.
