EDUCATION

•B.Sc. degree on Biological Sciences at the Federal University of São Carlos, Brazil (2001)
•PhD in Biological Oceanography at the Oceanographic Institute of the University of São Paulo (IOUSP), Brazil (2002-2007)
•Post Doc in MARUM (University of Bremen), Germany (2008-present)

RESEARCH INTERESTS

Link the microbial ecology to organic geochemistry on problems in the marine environment, with emphasis on the role of microbial communities mediating the cycle of carbon in the water column and sediments.

CURRENT RESEARCH

Employing a combination of molecular and stable carbon isotopic information from environmental carbon pools (e.g. total organic carbon, volatile fatty acids, intact membrane lipids) my current research is aimed at investigate the microbial carbon cycling in the marine realm. I am also interested in HPLC-ESI-MS in depth characterization of microbial intact polar lipids for assessing the physiological status and metabolic activities in cultures and enrichments.
