Eric Schmidt, Google’s executive chairman, is now on Mayo Clinic’s 31-member board of directors.

Schmidt joined the Mayo board last month, the clinic said.

Mayo is in the midst of a $5 billion expansion over the next 20 years; included is more than $500 million in state and local tax money to pay for  parking, transit, utilities and other public amenities.

Schmidt was Google’s chief executive officer from 2001 to 2011; now, as executive chairman, he’s responsible for the external matters of Google, such as “building partnerships and broader business relationships, government outreach and technology thought leadership, as well as advising the CEO and senior leadership on business and policy issues,” according to Mayo.

He’d been chairman and CEO of Novell and chief technology officer at Sun Microsystems, Inc. before joining Google.

The Mayo website’s list of board members hasn’t been updated to include Schmidt, but it also includes newsman Tom Brokaw as a trustee. The board includes Mayo doctors and administrators, as well as outside trustees.
