Her work focuses on the social side of computing, and she is known internationally for pioneering research in social visualization, interface design, and computer mediated interaction. She created several of the early social applications for the web, including the first postcard service (The Electric Postcard") and the first interactive juried art show ("Portraits in Cyberspace"). Her work with the Sociable Media Group has been exhibited at the Institute for Contemporary Art in Boston and in several New York galleries; she was the director of "Id/Entity", a collaborative exhibit of installations examining how science and technology' are transforming portraiture. Her current research focuses on creating expressive visualizations of social interactions and on building experimental environments that mix real and virtual experiences.

Professor Donath received her doctoral and master's degrees in Media Arts and Sciences from MIT, her bachelor's degree in History from Yale University, and has worked professionally as a designer and builder of educational software and experimental media.
