Mateos Lab

Interests:
Research in my lab focuses on two main aspects of evolutionary biology:

1. The evolution of host-symbiont associations using the association between
Drosophila flies and Spiroplasma bacteria. My interests span from
comparative genomics of bacteria with different fitness effects on the host,
functional genomics of both host and symbiont, and the evolutionary forces
that maintain this association.

2. Phylogeography of freshwater organims. So far I have focussed on
freshwater fishes (family Poeciliidae) in Mexico but plan to expand to other
organisms and regions.

Disciplines: Evolutionary & Population Genetics, Phylogenetics & Phylogeography,
Conservation Biology
