Greenberg to Take the Helm

This week, National Institutes of Health Director Francis Collins named Judith Greenberg acting director of the National Institute of General Medical Sciences. Greenberg will take the helm at NIGMS early next month as current Director Jeremy Berg departs the agency, though "the search continues for permanent director," the NIH says in a statement. "NIGMS will be in very able hands during this transition period," Collins said of Greenberg, who has been the project officer for the Human Genetic Cell Repository since 1984. "Not only does she have a long history of exceptional leadership at the NIGMS and NIH levels, she has already capably served a previous tour of duty in the acting director position," he added. Greenberg was acting director of NIGMS from May 2002 to November 2003.
