Cecilia R. Aragon

Cecilia R. Aragon is an American computer scientist, professor, and champion aerobatic pilot.[1][2] 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[3] 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 and her Ph.D. in computer science from the University of California, Berkeley. She is an associate 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-computer interaction include eScience, scientific and information visualization, visual analytics, image processing, collaborative creativity, analysis of spontaneous text communication, dynamic affect detection, and games for good.[4] Prior to her appointment at UW, she was a computer 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.[5]

Presidential Early Career Award

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.[6][7] She was recognized for "seminal research in workflow management and visual analytics for data-intensive scientific research, including the development of the Fourier contour analysis algorithm and Sunfall."[8]

Aerobatic career

Aragon first won a slot on the United States Aerobatic Team in 1991. She holds the record for shortest time from first solo in an airplane to membership on the US Team (less than six years),[9][10] and was also the first Latina to win a slot on the Team.

A team member from 1991–1994, she was a bronze medalist at the 1993 U.S. National Aerobatic Championships and the 1994 World Aerobatic Championships. She has also won over 70 trophies in regional aerobatic competitions at the Unlimited level and was California State Unlimited Aerobatic Champion in 1990. Aragon has also flown airshows (as distinct from aerobatic competitions) professionally since 1990.

Aragon has been a flight instructor since 1987. In 1989, she founded one of the first aerobatic and tailwheel flight schools in Northern California.[11] Aragon was a pioneer of "unusual attitude recovery training," where flight students are taught how to recover from emergency situations in flight. Until July 2009, she was an instructor at Tracy Airport, conducting aerobatic training, competition coaching, and teaching people to overcome their fear of flying.
