Giles will visit Cambridge next week to meet with Nieman staff. He will join the Foundation full-time in August.
The new curator says that he sees his responsibilities as head of the Nieman Foundation as two-fold.
"There are two major responsibilities," he said. "One is to do everything I possible can…to ensure that each of the fellows has an extraordinary year at Harvard and the second is to try to build on the great work that my predecessors have done in using the reputation of the Nieman Foundation and Harvard University to be an effective voice for journalism."
