Research Interests

I am interested in how (genetic underpinnings) and why (evolutionary reasons) animals are so diverse. To examine these questions, I integrate data from different scales, from molecules to organismal traits, and approaches, from field studies to large-scale genome sequencing analysis. Though I have worked in a variety of animal systems, from hummingbirds to fruit flies, fireflies, and the origins and evolution of their intriguing flash signals, are the system that has captured my scientific imagination.

  • Evolution of firefly flash signals and the genes underlying signal production and reception
  • Repetitive DNA evolution
  • Origin and evolution of bioluminescence in beetles
