A management professor with 14 years experience on the Air Force Academy faculty took over as the school's dean Tuesday.

Brig. Gen. Andrew Armacost, who has served as the head of the academy's Department of Management since 2008, will oversee academic programs for the school's 4,000 cadets.

Armacost has a bachelor's degree from Northwestern University in Illinois and earned his master's and doctorate degrees from the Massachusetts Institute of Technology. He's spent more than half of his Air Force career at the academy and also has served as the chief analyst for Air Force Space Command at Peterson Air Force Base.

"He's left an impression on thousands and thousands of cadets," said academy superintendent Lt. Gen. Michael Gould.

A management expert, Armacost has worked to align cadet programs with Air Force needs. While working at the academy, he oversaw a project that helped the Air Force find efficiencies in its use of transport planes to haul cargo.

Under Armacost, the school's management program has also helped the Air Force analyze plans involving work with sister services.

Armacost replaces outgoing dean. Brig. Gen. Dana Born, who retired from the Air Force and will serve on the faculty of Harvard's Kennedy School of Government.

Gould choked up during Tuesday's ceremony in saying farewell to Born, who had served as dean since 2004.

"We love you very much," Gould said. "We're going to miss your friendship."
