I received a Ph.D. in Bacterial genomics and evolution from the University of Lisbon in 2007 and I am currently leading the Eco-evolutionary Genetics Subgroup in the Evolutionary Ecology group of cE3c.
I am interested in knowing how interactions between organisms affect evolution. I use experimental evolution, with the nematode C. elegans and the bacterium E. coli. These two biological models will help understand how interactions between organisms influence adaptation and what is the molecular basis of these complex dynamics. The focus will be either on intra-population mechanisms, by which negative feedbacks can lead to the maintenance of genetic variability, or on interactions between species, where selective pressures occur between predators and prey or hosts and parasites.
In this context, I am interested in knowing:
Ultimately, my goal is to understand if what we know about the genetics of adaptation needs to be rethought in light of an evolving ecology.
