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 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 the effects of changing seasonality on migratory black-throated blue warblers, based during the summer months at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire. Ph.D. Cornell University, behavioral ecology
M.S. Michigan State University, ecology, evolutionary biology and behavior B.S. Iowa State University, zoology Postdoctoral research at the Cornell Lab of Ornithology, Smithsonian Migratory Bird Center, and Smithsonian Center for Conservation Genomics 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 managing threatened and endangered species projects 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.
