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
The Java Modeling Language (JML) is a formal specification language for Java that allows to express intended behavior through assertions. Currently, users must embed these assertions in Java comments, which complicates parsing and hinders tool support, leading to poor usability. This paper describes a set of proposed Java 5 annotations which reflect current JML assertions and provides for better tool support. We consider three alternative designs for such annotations and explain why the chosen design is preferred. This syntax is designed to support both a design-by-contract subset of JML, and to be extensible to the full language. We demonstrate that by building two tools: Modern Jass, which provides almost-native support for design by contract, and a prototype that works with a much larger set of JML.
