Dr. Vasey's work explores the behavioral ecology, life history adaptations, and evolution of primates, with a focus on the endangered and recently extinct primates of Madagascar. Natalie has presented her research at international venues, published in leading scientific journals, and edits a monograph series titled Primate Field Studies (Prentice Hall). She is dedicated to educating students and the public-at-large about the lifestyles and conservation status of our closest relatives in the Animal Kingdom. She is perhaps best known for her long-term work on red variegated lemurs of the Masoala Peninsula, Madagascar.
