Mariana Ferreira Da Silveira holds a Ms.C. in Oceanography at the Federal University of Pernambuco, Brazil (UFPE) and a B.S. in Marine Biology at Texas A&M University. 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 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. Currently, she is still working with artisanal fisheries in Brazil at Dr. Beatrice’s Lab (Oceanic and Reef Ecossystems Research Lab/LECOR - UFPE).
