ROCHESTER — Mayo Clinic has announced plans to more than double its research capability in Rochester.

The announcement came Tuesday night at a convention of international bioscience companies in San Francisco, California. Mayo Clinic CEO John Noseworthy and others revealed plans to build a 2 million-square-foot bioresearch campus in downtown Rochester.

The campus will be one of six districts to be developed in the Destination Medical Center, a public-private partnership. DMC board chairwoman Lt. Gov. Tina Smith says Rochester is well on its way to becoming “America’s capital of health.”

Mayo leaders said the development will bring together renowned physicians, researchers, scientists and entrepreneurs in a unique and innovative setting.

Construction is expected to begin in 2017 and be completed within two years.
