Dr. Cecilia R. Aragon Staff Scientist Visualization Group Computational Research Division Lawrence Berkeley National Laboratory Education: Ph.D., Computer Science, University of California, Berkeley;  Advisor: Prof. Marti Hearst M.S., Computer Science, University of California, Berkeley B.S. with Honors, Mathematics, California Institute of Technology Research Interests (previous): theoretical computer science. Aragon's early work was in theoretical computer science. With Raimund Seidel, she developed treaps, binary search trees in which each node has both a key and a priority, and randomized search trees, which use random priorities in treaps to achieve good average-case performance. With Johnson, McGeoch, and Schevon, she conducted the first extensive evaluation of the simulated annealing algorithm in combinatorial optimization problems. Research Interests (current): visualization, visual analytics, human-computer interaction, eye tracking. More recently, she has been working in visualization and analytics with applications to large scientific data sets. She developed an airflow hazard indicator for helicopter pilots that increased their ability to land safely during simulated hazardous conditions. With Bailey, Poon, Runge, and Thomas, she developed Sunfall, a visual analytics system for supernova astrophysics. Publications: She has published articles in peer-reviewed journals and conferences in both computer science and astrophysics. As of April 2008, her publications have been cited over 1300 times (per Google Scholar). She has won many awards for her work. Service: Aragon is also active in supporting diversity in computing. She is a founding member of Latinas in Computing, a member of the Computing Research Association's Committee on the Status of Women in Computing Research (CRA-W), and a member of the University of California Presidential Advisory Committee on the Status of Women.   Contact Info Cecilia R.
