Mariana Ferreira Da Silveira is currently a Ph.D. student at the Federal University of Bahia where she investigates the impacts of maritime enterprises (primarily related to oil, gas and offshore wind power) on the small-scale artisanal fisheries of Brazil. Mariana holds a M.Sc. in Oceanography at the Federal University of Pernambuco (UFPE), Brazil and a B.S. in Marine Biology at Texas A&M University (TAMU). In 2013, Mariana participated in TAMU's 1st Marine Biology Field Course in Galaxidi, Greece. Soon afterwards, she was involved in the management of the 1990–2013 bottlenose dolphin photo-identification catalogue stored at Dr. Bernd Würsig's Laboratory in Galveston, TX. In the following years, Mariana joined the Dolphin Biology and Conservation team as a field assistant, contributing to TAMU field courses as well as to field data collection in the Gulf of Corinth. Her masters' dissertation, under the supervision of Dr. Beatrice Padovani Ferreira, investigated a small-scale reef fishery in Northeast Brazil, in a context of intense transformations that included the establishment of a Marine Protected Area and socio-economic developments. She continued her work with artisanal fisheries ever since her masters, and also investigated the impacts of Brazil's largest coastal environmental disaster: an oil spill that occurred in 2019 and spread across more than two thousand kilometers of coast.
