A year of changes in the Yale Provost’s Office will come to an end this July when two new deputy provosts replace Pierre Hohenberg and Diana Kleiner.

Chemistry chairman Andrew Hamilton will join the provost’s office as deputy provost for science and technology, replacing Deputy Provost for Science and Technology Hohenberg. Barbara Shailor, director of the Beinecke Rare Book and Manuscript Library, will replace current Deputy Provost for the Arts Kleiner. Both Hohenberg and Kleiner will step down from their posts July 1.

“It’s always a challenge when very seasoned and wise members of the Provost’s staff leave — but I have every confidence that [Shailor] and [Hamilton] will be able successors,” Yale Provost Susan Hockfield said. “These are remarkable people, and I’m delighted they’ve decided to join the provost’s office.”

The departures of Hohenberg and Kleiner mark the first major changes in the office’s administration since then-provost Alison Richard appointed three new deputy provosts in 1995. Hohenberg and Kleiner both made their decisions to leave the office at the end of this year before Richard announced that she was leaving Yale for the University of Cambridge, Hockfield said.

For Hockfield, the changes will mark an opportunity to further integrate the different parts of the provost’s office.

“I’m hoping to build in the provost’s office an ever more cooperative team,” Hockfield said.

Hamilton said he was somewhat hesitant when Hockfield first approached him because he is heavily invested in his research program. But he said he hopes to keep his “foot on the accelerator” of the Science Hill project and help Yale to further shape its image in the sciences.

“It’s an exciting time, and so even with what I know will be pressures on my time, I hope I can contribute to the development of science at Yale,” Hamilton said.

Hamilton, who will continue his research after he steps into his new role, said he thinks it is important for the provost for science and technology to understand the challenges that face researchers. Hockfield said Hamilton’s research and his work with the Committee on Yale College Education will be valuable in the provost’s office.

“Since he’s been here, he’s really taken on a leadership role in a lot of different areas,” Hockfield said. “He also has a very deep understanding of Yale College.”

Since assuming her position in 2001, Shailor has worked not only to understand the library’s collections, but to make them more widely available, Hockfield said. Shailor’s work to collaborate with other University programs has been especially important, Hockfield said.

“She has shown the breadth of thought and energy and cooperative spirit that would characterize the finest people in the provost’s office,” Hockfield said.

Shailor said she will work to understand the problems facing different programs and departments at Yale and will continue her interdisciplinary approach at 1 Hillhouse Ave.

“I find that a very exciting adventure, and that’s something I’m hoping to build upon,” Shailor said. “[Hockfield’s] enthusiasm is infectious.”

Chemistry professor Gary Brudvig will be the interim chair of Chemistry until a new chair is appointed, while History professor Frank Turner will act as the interim director at Beinecke, Hockfield said.

Hamilton joined Yale’s faculty in 1997 from the University of Pittsburgh’s chemistry department. The chair of Yale’s chemistry department for four years, he also served on the biomedical sciences and coordinating committees of the academic review.

Shailor came to Yale in 2001 when she was appointed as the new director of Beinecke. Before coming to Yale, she served as the dean of Douglass College at Rutgers University after a 26-year tenure at Bucknell University.
