Fernanda B. Viégas is a research scientist and computational designer whose work focuses on the social, collaborative, and artistic aspects of information visualization.

Her fascination with the power of visualization to spark conversation led to the creation of Many Eyes with colleague Martin Wattenberg at IBM. The site is an open experiment on collective sensemaking and the impact of data analysis on public debate. Before joining IBM, Viégas’s research at the MIT Media Lab focused on the visualization of online communities. She is known for her pioneering work on depicting chat histories, email archives, and Wikipedia activity. Viégas's interest in the stories that people tell about these archives led to a series of visualizations of personal, emotionally-charged data. Her artistic visualizations have been exhibited in venues such as the New York Museum of Modern Art, the Boston Institute of Contemporary Art, and the Whitney Museum of American Art. Viégas holds a Ph.D. and M.S. from the Media Lab at MIT. She is from Rio de Janeiro, Brazil.
