Research Interests

My research focuses on the evolution, development, and function of morphological diversity. I primarily study bird feathers using a combination of theoretical modeling, museum collections, and fieldwork. My research projects include how feathers are used to fly, make colors, and produce sound, the role of feathers in the elaborate courtship displays of ‘bee’ hummingbirds, and the evolution and development of wing feathers across the evolutionary history of avian flight from feathered dinosaurs to modern birds.
