Washington (CNN) - Homeland Security Secretary Janet Napolitano announced Friday she is resigning and will be nominated to become president of the University of California system.
In an e-mail to associates, Napolitano said she will leave the Department of Homeland Security in September. While her nomination must be approved by the university's board of regents at a meeting next week, Napolitano sounded confident of the outcome.
"Departing a job and community you love is never easy, but I am passionate about educating the next generation of leaders and the University of California is like no other institution in affording such an opportunity," her e-mail said.
She graduated from the University of Santa Clara in California in 1979 as its first female valedictorian.
Napolitano, 55, was confirmed as the nation's third homeland security secretary and the first woman to hold the post the day after President Barack Obama took office in 2009.

New York (CNNMoney) - Kids lose their school IDs but they don't often lose their eyeballs.
That's one of the reasons why a growing number of schools are replacing traditional identification cards with iris scanners. By the fall, several schools - ranging from elementary schools to colleges - will be rolling out various iris scanning security methods.
Winthrop University in South Carolina is testing out iris scanning technology during freshman orientation this summer. Students had their eyes scanned as they received their ID cards in June.
"Iris scanning has a very high level of accuracy, and you don't have to touch anything, said James Hammond, head of Winthrop University's Information Technology department. "It can be hands free security."
The college will be deploying scanning technology from New Jersey-based security company Iris ID.
