Penn Engineering is the birthplace of the modern computer. It was here that the ENIAC, the world's first electronic, large-scale, general-purpose digital computer, was developed in 1946. Since this auspicious beginning more than five decades ago, the field of computer science at Penn has been marked by exciting innovations. Over the last few years, Penn CIS has grown in algorithms, theory of computation, networking, systems and architecture, and artificial intelligence. We are building on these successes to strengthen work on databases, graphics, programming languages, and security, and to deepen our interdisciplinary work in such areas as bioinformatics, cognitive science, robotics, and management.
