Princeton has been at the forefront of computing since Alan Turing, Alonzo Church, and John von Neumann were among its residents. The department, now in a period of major growth, has strong groups in artificial intelligence and machine learning, theory, programming languages, graphics and vision, systems and networking, computer architecture, computational biology and neuroscience, security, privacy, and information technology policy.
Bioengineers at Princeton bring together fundamental questions about how living systems work with an engineering approach to solving problems. While much work in bioengineering aims to improve human health, advances in the field also help address other global challenges, such as sustainable food, energy, water, and materials.
Data science accelerates discovery across nearly all areas of science, engineering, and social science. Students and faculty in this area create new data-analysis techniques and harness advanced computing and storage systems to solve problems in biology, the environment, materials science, communications, security, transportation, and many other areas.
Students and faculty in every engineering department bring their expertise to bear on securing our energy and environmental future. Much of this work comes together through the Andlinger Center for Energy and the Environment, which supports teaching and research in sustainable energy-technology development, energy efficiency, and environmental protection and remediation.
Entrepreneurship at Princeton, far more than starting profit-making companies, offers a powerful approach to education, service, leadership, and impact. The Keller Center offers a wide range of courses and programs in entrepreneurship and design thinking, while the Princeton Entrepreneurship Council provides coordination across the campus.
To be effective in solving critical societal problems, engineers must often work beyond purely technological domains and engage closely with policymakers. Several engineering faculty members are appointed jointly with the Woodrow Wilson School of Public and International Affairs and many others engage broadly on problems tied to policy. The Center for Information Technology Policy is a joint venture of the engineering school and the Wilson school.
The use of robots is moving rapidly beyond controlled environments such as factories to complex environments in the midst of human activity, demanding a nimble cross-disciplinary approach. Princeton engineers are advancing the productive, safe, and ethical use of robotics in society by building and connecting expertise in sensing, artificial intelligence, neuroscience, public policy, and other fields.
As digital systems play critical roles in nearly every aspect of society, their security and the privacy of their data become increasingly important. The Center for Information Technology Policy serves as a focal point for much of this work. In addition, engineers are uniquely positioned to improve broader areas of security in the face of natural hazards and other threats.
The world's metropolitan regions house over 50 percent of the world population, consume about 75 percent of worldwide energy, and emit about 80 percent of greenhouse gasses. By 2050, they will house about 70 percent of all people. Princeton engineers bring together expertise in the environment, infrastructure, climate, data science, sensors, privacy, security, public policy, and many other fields to make cities, towns and suburbs resilient and enjoyable places for people to flourish sustainably.
