The 2007 shooting spree that left 32 people dead at Virginia Tech changed the way college campuses are policed.

There is far more technology in play, closer relationships between police and and other campus services, and far higher expectations.

That's the landscape facing John H. Dailey, who today takes over as Duke University's new police chief.

This is a homecoming for Dailey, a Durham native who spent his summers as a kid working campus security at Duke.

Duke University has a new police chief.

He is John H. Dailey, a Durham native and former Duke police officer who most recently has worked as an assistant chief with the N.C. State University public safety office.

Dailey starts work April 1, succeeding Robert H. Dean, who retired last year.

Dailey worked at Duke from 1993 to 2001, working his way up the ladder from officer to sergeant to lieutenant and team leader. Eventually he became captain for administrative services.

He has been NCSU's assistant police chief since 2001.

Dailey got the law enforcement bug early in life. He spent his summers during high school and summer working as a Duke police security officer.

He attended Wake Forest University and later spent six years in the U.S. Army. He then received a master's degree in public administration from NCSU.
