SUSAN L. GRAHAM (NAE), Co-chair, is the Pehong Chen Distinguished Professor of Electrical Engineering and Computer Science at the University of California, Berkeley, and the chief computer scientist of the National Partnership for Advanced Computational Infrastructure (NPACI). Her research spans many aspects of programming language implementation, software tools, software development environments, and high-performance computing. As a participant in the Berkeley UNIX project, she and her students built the Berkeley Pascal system and the widely used program profiling tool gprof. Their paper on that tool was selected for the list of best papers from 20 years of the Conference on Programming Language Design and Implementation (1979-1999). She has done seminal research in compiler code generation and optimization. She and her students have built several interactive programming environments, yielding a variety of incremental analysis algorithms. Her current projects include the Titanium system for language and compiler support of explicitly parallel programs and the Harmonia framework for high-level interactive software development. Dr. Graham received an A.B. in mathematics from Harvard University and M.S. and Ph.D. degrees in computer science from Stanford University. She is a member of the National Academy of Engineering and a fellow of the Association for Computing Machinery (ACM), the American Association for the Advancement of Science (AAAS), and the American Academy of Arts and Sciences. In 2000 she received the ACM SIGPLAN Career Programming Language Achievement Award. In
