Earn a doctorate degree in critical infrastructure, advance scholarly research and your career

From hospitals to power plants, dams, water facilities, and transportation systems, critical infrastructure supports every aspect of our lives. The Department of Homeland Security has identified 16 critical infrastructure sectors whose assets, systems, and networks are so vital that incapacitation or destruction would debilitate the nation’s security, economy, public health, and safety.

While protecting these assets from physical threats has long been a concern, attention has only recently turned to the risk of a virtual attack. As security experts grapple with the implications of today’s Internet of Things, an urgent need exists for new research and ideas in the field. Through our doctoral program in critical infrastructure, you can contribute to solving one of the greatest technical challenges of the 21st century – how to create a robust and sustainable infrastructure that is resilient against multiple threats and hazards.
