For many years I was involved in a large-scale assessment of reef fish species over the Brazilian coast and oceanic islands. Marine underwater environments in Brazil were poorly understood and it was an exciting time for exploring these remote places and discovering new fish species and behavioural patterns. The coast of Brazil is very heterogeneous with regard to environmental conditions, presenting a distinctive north-south gradient from warm coral reefs to cool, upwelling-influenced rocky reefs. From my experiences working in this system, I became interested in understanding how the structure of fish communities changes in response to these different abiotic conditions. I thus carried my MSc. study on a subtropical mid-shelf reef to evaluate the effect of an additional major force on its reef fish community structure: exposure to large hydrodynamic forces and wave surge due to its offshore position. More recently, based on new research findings of reef fish richness and abundance patterns, both in Brazil and the larger Atlantic Ocean, I found myself particularly interested in large-scale comparisons among distinct marine biogeographical regions. In 2009 I joined the Computational Ecology Group as a Ph.D. candidate to conduct macroecological analysis of reef fish distributions over a wide range of locations within the Atlantic and Pacific oceans. Reef fishes represent the world’s largest and most diversified group of vertebrate animals and I expect that the outcome of these analyses may be applied to effective conservation and management of natural resources. Secondary to my research activities, I am also active in scientific outreach. As scuba dive instructor and underwater photographer, I enjoy giving marine biology seminars and writing magazine articles devoted to a non-scholarly audience. Additionally, I have been involved in management of dive tourism within Brazilian marine protected areas (MPAs).
