Susan Rice, United States ambassador to the United Nations, will be the commencement speaker during Ohio State’s 400th commencement ceremony June 10.

Rice, OSU’s final commencement speaker before the university switches to semesters, served as a foreign policy adviser for President Barack Obama before being appointed to the president’s cabinet, according to a university release.

“We are honored to have Ambassador Susan Rice address our graduates and their families at our largest Commencement ever,” President E. Gordon Gee said in the press release. “Ambassador Rice is a scholar, a leader on the international stage, and a fierce advocate for peace and human rights. Her extraordinary insights and life lessons will be the ideal epilogue to inspire the next generation of leaders.”

Rice, who will address about 10,000 students who will receive degrees during the commencement ceremony, has made efforts at the U.N. to help prevent the spread of nuclear weapons and provide aid to African countries.
