The Star Tribune on Thursday named Thomas Kupper, a senior editor since 2010, as assistant managing editor for business.

Kupper, 45, succeeds Todd Stone as the leader of the 21-person department, one of the largest business news teams among U.S. daily newspapers. Stone is leaving the Star Tribune to become a deputy managing editor at the Houston Chronicle.

Kupper has been responsible for the Star Tribune's Sunday business section and coordinated many of the department's major projects, including stories on Minnesotans left behind in the economic recovery and soaring prices for agricultural land in the state.

Before joining the Star Tribune, Kupper spent 13 years as a business reporter and editor at the San Diego Union-Tribune. He has an MBA from UCLA and a bachelor's degree from Northwestern University.

As a reporter, he was a finalist for the Livingston Award, which honors the best work in the country by journalists under 35. As deputy business editor in San Diego, he oversaw a real estate section that was named the best in the country by the National Association of Real Estate Editors.
