Originally from Mozambique, Kátya is an aquatic ecologist with experience working in rivers and estuaries of Australia, East Africa and the Pacific Islands. Her research is mostly related to the identification and quantification of impacts of different human activities (e.g. urbanization, deforestation, flow regulation, agriculture, introduction of exotic species) on the aquatic ecology. She also works on animal movement, particularly in questions related to migration patterns and habitat use of bony fish and sharks; to the identification of critical habitats for fisheries species so that the best habitats to protect, preserve or restore can be identified; and to the development of fisheries best practices.
