I'm an evolutionary biologist, interested in bacterial social interactions and co-evolution with their hosts and their own symbionts, especially plasmids and other mobile genetic elements.

My PhD focused on horizontal gene transfer from a social evolution perspective, aiming at understanding the selective pressures acting on plasmid transfer and the interaction of horizontal transfer with public good production. I explored these questions with both modelling and controlled experiments using synthetic bacterial strains where transfer and public good production are controlled and quantified.

For my postdoc in Ben Raymond’s group, I have moved to studying bacterial evolution in more complex and realistic systems. I am currently working on Bacillus thuringiensis, a pathogen of insects which virulence is mostly based on social behaviours. I am performing experimental evolution experiments, in order to analyze the evolution of strains that overcome insect host resistance.
