NASA opens Planetary Defense Office to protect earth from asteroids

I was wondering whether such an office or team existed only the other day. And then came across this at Space.com:

NASA has announced the creation of a Planetary Defense Coordination Office (PDCO). Lindley Johnson, NASA's current near-Earth object (NEO) program executive will lead the newly established office. The PDCO will reside within NASA's Planetary Science Division, in the agency's Science Mission Directorate in Washington, D.C. ...Planetary defense duties

What will the office do? It will be responsible for: Supervision of all NASA-funded projects to find and characterize asteroids and comets that pass near Earth's orbit around the sun;Lead the coordination of interagency and intergovernmental efforts to plan response to any potential impact threats.Improve and expand on past efforts with other U.S. federal agencies and departments, such as the Federal Emergency Management Agency (FEMA).Continue to assist with the coordination across the U.S. government, including planning for response to an actual impact threat and working in conjunction with FEMA, the Department of Defense, other U.S. agencies, and international counterparts.Issue notices of close passes and warnings of any detected potential NEO impacts, based on credible science data. 

Good. I feel a little safer. A little. What job does Bruce do?
