Alexandra L. DeCandia, Ph.D.Assistant Teaching Professor
Department of Biology, Georgetown University Assistant Director Regents STEM Scholars Program, Georgetown University Research Associate Center for Conservation Genomics Smithsonian's National Zoo & Conservation Biology Institute Alexandra (Allie) DeCandia joined Georgetown University in August 2021 as an Assistant Teaching Professor [CV]. As a researcher, Allie applies tools and concepts from molecular ecology, disease ecology, and conservation biology to inform wildlife management in captivity (e.g., black-footed ferrets) and the wild (e.g., Channel Island foxes and Yellowstone National Park wolves). As an educator, she applies a student-centered learning approach to actively engage students and trainees with material, while equipping them with skills and confidence to pursue scientific exploration. As a communicator, she shares her love of science with elementary through high school students through classroom visits, with the public through non-technical science writing, and with colleagues through peer-reviewed articles and presentations at scientific conferences. Outside of her work, her favorite activities include hiking (especially in National Parks!), exploring new cities, experimenting in the kitchen, and finding creative ways to be more eco-friendly. |
