Principal Investigator
Dr. Sara Kaiser
I am a Research Ecologist and the Director of the Hubbard Brook Field Ornithology Program at the Cornell Lab of Ornithology and maintain my status as a Research Associate at the Smithsonian Conservation Biology Institute.
My research program provides training and research opportunities for undergraduates and postdoctoral researchers as part of my ongoing research on migratory black-throated blue warblers, based during the summer months at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire, and grasshopper sparrows in the Caribbean Islands. My training includes a Ph.D. from Cornell University in behavioral ecology, an interdisciplinary M.S. from Michigan State University in ecology, evolutionary biology and behavior, and a B.S. from Iowa State University in zoology. I conducted postdoctoral research at the Cornell Lab of Ornithology, Smithsonian Migratory Bird Center, and Smithsonian Center for Conservation Genomics where I expanded my expertise in modern molecular approaches for understanding animal behavior and ecology.
Prior to my doctoral training, I taught field courses as a Faculty Instructor of Conservation Biology in New Zealand and worked as an Avian Ecologist on the California Channel Islands in island bird conservation. |

Current Students
My highly motivated students have conducted independent research on a variety of topics.
Student field projects have included lab components during the academic year and leveraged long-term data (behavioral, genetic, environmental) collected as part of long-term population studies. I encourage my students to develop original research, to write grant proposals to support their research, and to submit senior theses and scientific publications to further their development as scholars.
