Francisco Dionísio

Main Research Interests

My main research interests are evolutionary ecology of microorganisms, with a focus on bacteria, viruses and plasmids. I study cooperation, competition, spite, mutualisms and sex in the microbial world, and their impact on pathogenicity and drug resistance. Evolutionary consequences of DNA conflicts in several systems, including plasmidic DNA and chromosomal DNA. My approach involves both laboratory work and theoretical research.

 

Academic Qualifications

- 2000 PhD in Microbiology (Paris VII University, Paris, France)

- 1995 5-year college graduation in Physics (Instituto Superior Técnico, Lisbon)
