Samantha Phillips, director of the Office of Emergency Management in Philadelphia, is leaving the city for a new job leading the National Center for Security and Preparedness in Albany, N.Y., Mayor Kenney announced Friday.

Phillips joined the city's emergency-management office in 2007 and became its director in 2011. In that position, she oversaw the city's handling of the Democratic National Convention last year and Pope Francis's visit in 2015 as well as the city's response to the Amtrak train derailment in 2015 and the Market Street building collapse in 2013.

Her resignation takes effect at the end of this month. She will thereafter serve as director of the Albany research center, which is part of the College of Emergency Preparedness, Homeland Security and Cybersecurity at the University at Albany.

Kenney named Dan Bradley, deputy director for operations at the Office of Emergency Management, as acting director while the city searches for a replacement for Phillips.
