Education
Fonseca’s academic foundation includes a Doctorate in Geology (2008) and a Master’s degree in Geology (2004), both from Universidade Federal Fluminense, where he also completed a postdoctoral fellowship in Environmental Geology in 2010. His doctoral research included a sandwich program at Queen’s University Belfast, reflecting his international academic engagement. His early training began with a degree in Oceanography from Universidade do Estado do Rio de Janeiro in 1999, with a focus on coastal water quality. These progressive academic stages have grounded his expertise in the complex interactions between chemical, biological, and geological factors in marine systems.
Experience
Professionally, Fonseca’s trajectory includes academic and technical roles that bridge academia and applied environmental science. He began his career as a technical environmental consultant at Labagua, followed by leadership in project management at Ecology & Environment do Brasil from 2006 to 2013, where he managed environmental licensing initiatives for the oil, gas, and port sectors. Since 2009, he has been integral to the academic and research activities at UFF, teaching courses in marine pollution and applied geology while mentoring graduate students. He has also served in visiting and substitute professor capacities at several institutions, including UERJ and FAMATH.
Research Interests
Fonseca’s research interests center on marine pollution, particularly the behavior and fractionation of heavy metals in sediments and their bioavailability to microorganisms. His scientific inquiries extend to the impacts of microplastics and endocrine-disrupting chemicals in aquatic ecosystems. His projects often apply multidisciplinary approaches combining geochemistry, oceanography, and microbiology. Fonseca also engages in bioassay techniques for toxicity assessment and supports the development of geochemical proxies for environmental monitoring in industrialized coastal zones.
Awards
Among his many accolades, Fonseca is the recipient of a CNPq Level 2 Productivity Researcher Grant, a prestigious recognition of sustained research excellence in Brazil. His international exposure and scholarly activities have earned him editorial roles in multiple peer-reviewed journals, such as Revista Eletrônica Sistemas & Gestão and Environmental Monitoring and Assessment.
