In 2006, Rush was appointed the Henry and Lois Foster Director of the Rose Art Museum at Brandeis University in Waltham, Massachusetts.[1] In January 2009, Rush was at first "shell-shocked" by the surprise announcement of plans to permanently close the Rose Art Museum and sell off its collection, but he soon organized some of the initial opposition to the scheme.[4] His employment contract with Brandeis was not renewed in June 2009, effectively forcing him to leave.[5] Ironically, he had been principal contributor to a substantial book commemorating the 50th anniversary of the Rose Art Museum and featuring its collection, which was published by Abrams Books in late 2009.[6]
