Dr. Daniel Hanley is Assistant Professor of Biology at George Mason University. He studies visual perception, cognition, and decision-making in wild birds. By quantifying the diversity of colors found in nature (particularly birds’ eggs), his laboratory addresses fundamental questions about how selection pressures shape the evolution of phenotypes, and how those phenotypes govern species interactions. His work has been published in more than 40 peer-reviewed journals such as Nature Ecology & Evolution, Proceedings of the Royal Society, the American Naturalist, and Biology Letters and is frequently highlighted by the popular press (e.g., as Audubon, the BBC, and Science magazine). In August 2020, Dr. Hanley was awarded Elective Membership at the American Ornithological Society for significant contributions to ornithology and the society.
