Kohlberg Kravis & Roberts, with offices on 57th Street near 6th Avenue, tapped Petreaus to lead its newly-created Global Institute, which will help guide the firm's overseas investments, particularly in new and emerging markets, KKR said in a statement.
"As the world changes and we expand how and where we invest, we are always looking to sharpen the 'KKR edge,'" KKR co-founder and co-CEO Henry Kravis said in a statement. "With the addition of General Petraeus, we are building on the work we have done to understand the investment implications of public policy, macro-economic, regulatory and technology trends globally."
Petreaus, 60, called the new appointment "a very exciting prospect."
The general has been carefully rebuilding his reputation since resigning from his CIA post last November, an event triggered by an extramarital affair with his biographer, Paula Broadwell, that became public.
In April, he was named a visiting professor for public policy at the City University of New York, a job that will begin this August.
He also serves on the advisory council of American Corporate Partners as well as the faculty of the University of Southern California, and he has previously taught at West Point.
He holds a PhD in international relations from Princeton University.
