Cecilia Rodriguez Aragon (born ca. 1960) is an American computer scientist, professor, and champion aerobatic pilot. In computer science, she is best known as the co-inventor (with Raimund Seidel) of the treap data structure, a type of binary search tree that orders nodes by adding a priority as well as a key to each node and for her work in data-intensive science and visual analytics of very large data sets, for which she received the prestigious Presidential Early Career Award for Scientists and Engineers (PECASE).
Aragon received her B.S. in mathematics from the California Institute of Technology in 1982, her M.S. from the University of California, Berkeley in 1987 and, her Ph.D. in computer science from the same institution in 2004. She is a professor in the Department of Human Centered Design and Engineering at the University of Washington in Seattle. Her research interests in the field of human-centered data science include eScience, scientific and information visualization, visual analytics, image processing, collaborative creativity, analysis of spontaneous text communication, dynamic affect detection, and games for good. Prior to her appointment at UW, she was a computer scientist and data scientist at Lawrence Berkeley National Laboratory for six years and NASA Ames Research Center for nine years, and before that, an airshow and test pilot, entrepreneur, and member of the United States Aerobatic Team.
On July 9, 2009, Aragon received a Presidential Early Career Award for Scientists and Engineers, the highest honor bestowed by the United States government on outstanding scientists and engineers in the early stages of their independent research careers.
