I am interested in host-microbiota relationships in fishes in an evolutionary context. 

Ongoing projects

(COMING SOON)

Past projects

Discus (Symphysodon sp.)
Discus Microbiota Project (M.Sc.; 2015-2018)
​My master's project is about the recruitment of symbiotic bacteria in the intestinal microflora of the Discus (Symphysodon sp.), an Amazonian fish of high commercial value that feeds its offspring  with cutaneous mucus during the first few weeks of life. My master's project involves expertise in the following fields: genomics, metagenomics, population genetics, evolution, aquaculture and microbial ecology.
