Feinstein was the inaugural dean at Indiana University's Lee H. Hamilton and Richard G. Lugar School of Global and International Studies.
Feinstein was a presidentially appointed trustee of the United States Holocaust Memorial Council and currently serves as vice-chair of its Committee on Conscience, which advises the museum’s Simon Skjodt Center for the Prevention of Genocide.
Feinstein, in his museum capacity, participated in two trips to Myanmar and refugee camps in Cox's Bazar in Bangladesh and raised concerns with Burmese authorities in Naypydaw.
Feinstein also served as an advisor to the congressionally mandated Task Force on the United Nations, chaired by former Speaker of the House Newt Gingrich and former Senate Majority Leader George J. Mitchell.
As ambassador, Feinstein joined with the Polish government and civil society to promote democracy in the region, advanced deeper understanding of contemporary Poland in the United States, and supported civil society in the country, including hosting the parents of Matthew Shepard and introducing them to Polish parents of LGBTQ children.
Feinstein was named the founding dean of Indiana University's School of Global and International Studies in 2014, a post he no longer holds.
In 2018, Feinstein played a major role in having the school renamed after the bipartisan foreign policy leaders and long-time Indiana Members of Congress Senator Richard Lugar and Congressman Lee Hamilton.
In 2020, the university and school were designated as a “top performing institution” in the number of Boren Awards won by its students, tied for second in the nation.
Feinstein has recruited many prominent foreign policy voices and scholars to address the Hamilton Lugar school at the student-focused America’s Role in the World Conference, which he founded in 2015, ranging from Rohingya Burmese activist Wai Wai Nu to IU alumnus and former defense secretary Robert Gates to Senator Todd Young who delivered the inaugural Lugar lecture and former US Ambassador Marie Yovanovitch.
