Welcome to the Castillo Lab

We are a brand new group starting in the School of Biological Sciences at the University of Utah. Our aim to answer fundamental questions about how natural and sexual selection shape mating interactions and behaviors, species interactions, and ultimately speciation.

We use an integrative approach combining population and molecular genetics with behavioral experiments to understand the genetic basis of sexual behaviors and reproductive isolation. We also incorporate comparative genomics of reproductive isolation to analyze repeated evolution of reproductive isolation across the tree of life. By studying the mechanistic and genetic links between sexual selection and reproductive isolation we can determine the influence of these forces on generating biodiversity

We are looking for passionate new PhD students and Postdocs to join the team (more info) !
