Research Interests
Evolution of visual systems and visual communication: genetics of visual system tuning; physical modeling of color signals and visual discrimination. African cichlid fishes serve as a model to explore how natural and sexual selection drive communication. Evolution of rod and cone phototransduction: tuning photoreceptor responsivity through evolution of protein structure and gene expression. A comparative genomic approachutilizing a diversity of vertebrates including mammals, reptiles, amphibians, fish, and agnathans.
