Sam Davis, professor emeritus of architecture, will be interim dean of the College of Environmental Design.
J. Keith Gilless, professor of forest economics, will be dean of the College of Natural Resources.
Richard Lyons, professor at the Haas School of Business, will be dean of the business school. Lyons has been the chief learning officer at the Goldman Sachs investment bank in New York City while on leave from the Haas School.
Richard Mathies, professor of chemistry and director of the campus' Center for Analytical Biotechnology, will be dean of the College of Chemistry.
Mark Schlissel, professor of immunology, biochemistry and molecular biology, will be dean of the division of biological sciences within the College of Letters & Science.
Diana Wu, formerly the acting dean of the University Extension, will be dean of the University Extension.
In a statement, UC Berkeley Executive Vice Chancellor and Provost George Breslauer said, "We are delighted about the appointment of this stellar cohort of deans. These talented and accomplished individuals are recognized leaders in their fields and UC-Berkeley is very fortunate to have them."
Breslauer lauded the depth and breadth of the new deans' expertise, saying it "will enhance the disciplines and programs they represent, advance the interests of their individual schools and colleges, and serve well the university, its multiple constituencies, and the broader higher education community."
In addition to the six new deans announced this week, John Quigley, professor of economics, will serve as interim dean of the Goldman School of Public Policy, pending approval of his compensation, while the campus continues its search for a new dean.
Except for Wu, who's at the University Extension, the deans all are UC Berkeley professors. Each new position is retroactive to July 1.
UC officials said the new deans replace outstanding scholars who have retired, chosen to return to the faculty ranks or moved to other institutions.
The Board of Regents approved the appointments at its meeting at UC Santa Barbara on Thursday.
