Dr. Salerno is a marine biologist and microbial ecologist working at the intersection of science and policy.  Dr. Salerno’s research interests focus on symbiotic and free-living microorganisms and the role that they play in maintaining and destabilizing organism health and ecosystem function. Recognizing the important link between human health and ecosystem health, this research is approached through the lens of seeking to advance basic science, while also developing environmental monitoring tools, practical applications, and policy guidance for environmental resource management and conservation. The Salerno Laboratory is currently working on projects pertaining to coral and fish disease, interactions between microbes and microplastics, and microbes as biological indicators of aquatic health.
Dr. Salerno also engages in science communication and interdisciplinary work at the intersection of science, policy, and diplomacy. She previously worked on coastal and ocean issues in the U.S. House of Representatives as a NOAA Sea Grant Knauss Fellow and served as an American Association for the Advancement of Science (AAAS) Science and Technology Policy Fellow at the U.S. Department of State, Bureau of East Asian and Pacific Affairs, Office of Economic Policy.

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.
