The realization that wind turbines and freight trains have a lot in common changed the trajectory of Warren Powell's career. After decades of work making the transportation industry more competitive and environmentally friendly, Powell has turned his attention to the energy industry. "It's all about resource allocation, whether you need to assign trains better or need to decide how many wind turbines to keep running."

Thwarting Terrorism: Making sense of sensors: Researchers aim to improve detection of nuclear threats
Sensor technology is greatly advancing the ability to detect dangerous material. But how do we collect and interpret information as quickly as possible to respond to threats without generating false alarms? Princeton researchers are part of a $2 million grant from the National Science Foundation and the U.S. Department of Homeland Security for research on optimizing the management of sensors used in ports, on roadways and in the air to identify smuggled nuclear material that might be used to cre
