Our Team

  • Abigail Ross, PhD, Executive Director

    Abby decided to turn her life-long enthusiasm for nature into a career when as a college freshman she chaperoned a high school trip to the Galápagos Islands. Abby is a primatologist and earned her PhD in Evolutionary Anthropology from the University of Toronto. Her research broadly focuses on maternal care, environmental endocrinology, and nutritional ecology in lemurs.

    She has participated in conservation projects in Bolivia, Costa Rica, Equatorial Guinea, Madagascar, and South Africa. Her mentorship of Malagasy graduate students galvanized TDARFAC’s creation and first inspired Abby to advocate for conservation action in 2010.

    “Sentiment without action is the ruin of the soul.”
