As the Detroit Institute of the Arts plows ahead with a major expansion project, slated to be completed in 2006, the museum is also undergoing some major changes behind the scenes. Earlier this year, the DIA laid off 55 staffers, and now, a shuffling of curator positions is reportedly causing some grumbling. The curatorial changes will see some departments combined, and others expanded. Some longtime curators are being reassigned to positions which could be seen as less prominent. DIA’s chief curator says that the changes are merely meant to streamline the museum’s operations.
