Chris Johnson, a distinguished professor of computer science and director of the Scientific Computing and Imaging Institute, has been elected by his peers as a fellow in the American Association for the Advancement of Science. Johnson is one of 376 AAAS members who were given the distinction this year "because of their efforts toward advancing science applications that are deemed scientifically or socially distinguished," the group says. Johnson specifically was cited "for distinguished contributions to scientific computing and scientific visualization." The AAAS, founded in 1848, is the world's largest general scientific society and publisher of the journal Science, which has an estimated total readership of 1 million.
