Adaptation and Speciation

A major focus of my current research is on the evolutionary and ecological consequences of interspecific interactions in various systems. Research started during my PhD focuses on how adaptations to divergent selective regimes lead to reproductive isolation and speciation. This research has focused on multiple lineages of fishes in the family Poeciliidae that have adapted to live in toxic hydrogen sulfide (H2S) springs across the Americas and Caribbean Islands. I also used this system to test for convergent adaptation across levels of biological organization in replicated lineages evolving in response to these shared selective regimes.
