Short Bio

I am currently a PhD student at the Evolutionary Biology Group in the IGC. I graduated in Biology at Faculdade de Ciências da Universidade de Lisboa. I also did there my Masters in Applied Microbiology, although my thesis was done in Faculdade de Farmácia da Universidade de Lisboa, working on the genetic basis of the Esat-6-like secretion system in Bacillus subtilis. After my Masters I worked in a collaboration between the Microbial Development Lab in ITQB-UNL and the Evolutionary Biology Group in IGC, looking at the first steps of adaptation into the laboratory environment of a wild strain of Bacillus subtilis isolated from the gut.

Research Interests

I am interested in studying how gut bacteria perceive environmental changes and adapt to it, specifically within the context of aging. Understanding the importance of the interactions between gut bacteria and their influence in the gut ecosystem, as well as the effect of ecosystem alterations in bacterial evolution are also part of my interests.
