Postdocs
Conor Taff
Conor joined the lab as a Cornell Lab of Ornithology Rose Postdoctoral Fellow, and is now supported by a DARPA grant on how social interactions influence stress resilience. Before coming to Cornell, he completed a PhD and USDA-funded postdoctoral research at the University of California, Davis. Conor has been studying wild birds for over 10 years. His work has addressed questions about breeding biology, life history trade-offs, sexual signal evolution, epidemiology, and movement ecology in Common Yellowthroats, Greater Sage-Grouse, and American Crows. Conor's current work, in Tree Swallows, addresses how stress affects behavior and physiology, and how social signals and social interactions affect phenotype and fitness. You can read more about Conor's research here.
Cedric Zimmer
Cedric is a postdoctoral researcher in the lab. Before coming to Cornell he completed a PhD at the University of Strasbourg in France, and a postdoc at the University of St. Andrews in Scotland. Cedric has been working on stress in birds for over a decade. His work addresses how stressors (including predation risk, food availability, and anthropogenic disturbance) affect birds, and the adaptations that enable successful coping. He is especially interested in the effects of developmental stressors exposure on later-life phenotypes. Cedric's work uses an interdisciplinary approach that combines techniques from molecular biology to behavioral ecology. Read more about Cedric's work here.
Allison Injaian
Alli is a postdoctoral associate in EEB and a Rose Fellow at the Lab of Ornithology. She earned a PhD in Animal Behavior from the University of California, Davis and a MS in Ecology and Evolution from the University of Michigan. Alli is generally interested in human impacts on birds. Her doctoral research experimentally tested the effects of traffic noise exposure on habitat use, parental behavior, adult and nestling physiology, reproductive success and telomere dynamics in tree swallows. In the Vitousek Lab, Alli will continue working with tree swallows by experimentally investigation light pollution impacts on adult and nestling physiology and immune responses. She will also investigate anthropogenic noise propagation through complex habitats. To find out more, visit Alli's website here.
Sabrina McNew
Sabrina is a Rose Postdoctoral Fellow working with the Vitousek and Lovette Labs. She joined the Lab of Ornithology after completing a PhD at the University of Utah. Sabrina’s research interests focus on avian disease ecology and tropical ecology. During her PhD, Sabrina studied the effects of an introduced parasite, Philornis downsi, on Galápagos mockingbirds. Her work integrates field experiments, genomic and epigenomic tools, and immunology to understand how birds defend themselves against parasites and pathogens. In the Vitousek Lab, Sabrina looks forward to developing experiments in a new system and learning more about stress physiology. More information about her research can be found at sabrinamcnew.com
