NEW YORK (AP) - Ex-CIA director David Petraeus is replacing one kind of intelligence work with another.

Macaulay Honors College at City University of New York said on Tuesday the retired four-star general has been named a visiting professor for public policy.

He starts on August 1.

General Petraeus has a doctorate from Princeton University and has written widely on international relations, military strategy and tactics and national security issues.

He says in a statement released by Macaulay that he's pleased to teach at the college, where most students are children of immigrants.

He says he looks forward to leading a seminar on the global economic slowdown.

General Petraeus was a hero of the Iraq and Afghanistan wars. He left the CIA in scandal last November after it was uncovered he'd had an affair with his biographer.
