​​​Current Research Projects
We are interested in the evolution of phenotypic diversity. More specifically, we study the role of physiology in color signalling, competition, and speciation. As the most diverse group of vertebrates, cichlids are an important model system in evolutionary biology. Furthermore, their complex yet tractable social behavior has also led to their widespread use as a model system in neuroethology. We are currently studying how stress during development influences to expression of fitness-related traits such as body pigmentation and aggressive behavior. Specific areas of research interest include:
  • Behavioral Ecology
  • Animal Physiology
  • Endocrinology
  • Evolution
