Catalina is a Marine Social Science researcher. An anthropologist by heart and training, she has worked at the Colombian Erigaie NGO as an independent researcher and consultant in marine social sciences for over two decades. Her research, situated in critical ocean studies, focuses on ocean justice and marine governance in contested marine areas. Currently, Catalina is a doctoral student in the Geography and International Development Department at the University of Amsterdam, the Netherlands. From the perspective of maritime legal geographies, she looks at the role of Black and Indigenous legalities in governing the ocean in equitable and sustainable ways, and the extent to which they are integrated into the international ocean regimes. In particular, she works with the Black-Creole communities in the islands located on the Nicaraguan-Colombian contested border area, exploring the indigenous marine laws and their forms of resisting international regimes through indigenous rights regarding artisanal fisheries, sea mobility, and marine environmental resource management.
