Ellen Zegura works in two primary areas, computer networking and computing for public good. In computer networking, she is known for her work on the GT-ITM suite of Internet topology tools, which remain in use 20 years after release (2400+ citations for primary publication). In mobile wireless networking, she and colleagues invented the concept of message ferries to facilitate communications in environments where network connectivity is unreliable and/or sparse (1600+ citations for primary publication). Her work in computing for public good includes work in Liberia with the Carter Center, with Native Americans in Southern California, and with residents of the Westside of Atlanta.
Ellen Zegura teaches across multiple areas of the curriculum, including computer networking, computing and ethics, and discrete math. She has taught on the Atlanta campus and three times in the summer program in Barcelona.
