President Obama’s top anti-terrorism chief will deliver an address in Dublin this week on security cooperation between the US and Europe.

Irish American John Brennan, whose grandparents hailed from Co. Roscommon, was appointed as Obama's chief counterterrorism advisor in May 2009.

In one of the most iconic American images of recent years, Brennan was snapped alongside the President in the White House Situation Room, while the security team watched the raid that killed Osama Bin Laden.

“We're not going to rest until al Qaeda the organization is destroyed and is eliminated from areas in Afghanistan, Pakistan, Yemen, Africa, and other areas. We're determined to do that,” Brennan told ABC’s This Week in April.

One of Obama’s top aides, Brennan will be in Dublin this coming Friday to give a talk at the Institute of International and European Affairs (IIEA), in the north side of the city.

According to IIEA, Brennan will deliver an address titled “U.S. and Europe: Security Cooperation and Shared Challenges,” in which he will share his unique perspective from the Obama White House on transnational security challenges facing the United States and Europe and the international cooperation required to deal with them.

IIEA is an Irish based think tank on European and International affairs and is an independent not-for-profit organisation.

A New Jersey native, Brennan followed the well-worn Irish Catholic path, graduating from Fordham University in 1977, a period which included a study abroad program in Cairo. He went on to earn an MA from the University of Texas before he joined the CIA as an intelligence director in 1980.
