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 spread of infections (disease, ideas, fires, etc.) in a network (group of people, electronic network, forest, etc.) can be modeled by the evolution of states of nodes in a graph defined as a function of the states of the other nodes in the graph. Given an initial configuration of the graph with a subset of the nodes infected, a propagation function that specifies how the states of the nodes change over time, and a quarantine function that specifies the generation of regions centered on the infected nodes, from which the infection cannot spread; we identify and verify intervention policies designed to contain the propagation of the infection over the network. The approach can be used to determine an effective policy in such a scenario.
