My research is based on Evolutionary Genomics and Microbial Data Science to understand the association between gain/loss of genes and the colonization of new niches/environments. I am particularly interested in applying network analyzes to complex biological datasets.

Currently, I am a Computational Biologist at Finch Therapeutics's Data Science team working on human gut microbiome!

My research experience comprehend:
  • Evolutionary Genomics;
  • In-silico protein annotation;
  • Human Microbiome;
  • Molecular evolution;
  • Statistical analysis of biological data;
  • Statistical clustering;
