Computer Science—the theory, representation, processing, communication and use of information—is fundamentally transforming every aspect of human endeavor. The Department of Computer Science at Iowa State University advances computational and information sciences through; 1. educational and research programs within and beyond the university; 2. active engagement to help define national and international research, and 3. educational agendas, and sustained commitment to graduating leaders for academia, industry and government.
History
The Computer Science Department was officially established in 1969, with Robert Stewart serving as the founding Department Chair. Faculty were composed of joint appointments with Mathematics, Statistics, and Electrical Engineering. In 1969, the building which now houses the Computer Science department, then simply called the Computer Science building, was completed. Later it was named Atanasoff Hall. Throughout the 1980s to present, the department expanded and developed its teaching and research agendas to cover many areas of computing.

Abstract
Aspect-oriented advice increases the number of places one must consider during reasoning, since advice may affect all method calls and field accesses. MAO, a new variant of AspectJ, demonstrates how to simplify reasoning by allowing programmers, if they choose, to declare limits on the control and heap effects of advice. Heap effects, such as assignment to object fields, are specified using concern domains--declared partitions of the heap. By declaring the concern domains affected by methods and advice, programmers can separate objects owned by the base program and by various aspects. When desired, programmers can also use such concern domain annotations to check that advice cannot interfere with the base program or with other aspects. Besides allowing programmers to declare how concerns interact in a program, concern domains also support a simple kind of semantic pointcut. These features make reasoning about control and heap effects easier.
