PhD candidate in the group of Prof. Walter Salzburger
As biologist graduated at the Brazilian littoral, my interests always surrounded the biology of aquatic life, and over the years I have been able to translate my fascination for nature into a research career in the fields of wildlife conservation, evolutionary biology, molecular ecology and population genomics. During my internship and master’s I investigated seafood mislabeling in the southern Flounder, discovering several mismatches on sequences databases that created erroneous phylogenetic inferences, which I corrected by building an accurate integrated molecular database. In addition, some of my work has focused on the identification of the conservation status of two vulnerable Flounder species explained by overfishing and ultimately caused by poorly planned fishing policies, culminating in an effective change on label regulations that better reflect this species conservation status.
During my PhD in the Salzburger group, I am interested in how genetic diversity of cichlid fishes is shaped during the millions of years of species diversification. Genetic diversity is of paramount importance for adaptation and long-term species survival, including adaptation to environmental changes, especially in order to resist to the increasing anthropogenic impacts. However, the importance of diverse life history traits and demographic processes in shaping this genetic diversity – and thus impacting adaptation and survival – are not yet fully understood. Using both life history traits and genomic population data of at least 30 species of cichlid fishes, representing all the different tribes from African Lake Tanganyika, I will initially investigate how the species population’s structure and size fluctuate along their diversification to determine the impact of past environmental perturbations onto genetic diversity and its role in the incredibly diverse cichlids traits specialization.
