Rackham Graduate School announces the 2025 ProQuest Distinguished Dissertation Award winners

April 24, 2026

Two Ford School graduates were recognized by Rackham Graduate School for their doctoral dissertations. Benjamin Goehring (PhD '25) was one of 10 winners of the ProQuest Distinguished Dissertation Awards (DDA). Owen Kay (PhD '25) received an honorable mention for his dissertation "Essays on Optimal Energy Policy." 

Goehring's dissertation "The States of American Bureaucracy" is a valuable contribution to the study of public administration. Using a database of personnel records across several states, Goehring rigorously examines the causes of turnover within state governments with a focus on civil service protections and working conditions. He finds no evidence in Mississippi or Florida that rolling back tenure protections led to the systematic purging of political opponents. However, the removal of tenure protections did lead to an increase in turnovers, particularly among longer-serving employees. In addition, Goehring's analysis of Texas prisons found a significant correlation between excessive heat and turnover among correctional officers. 

Charles Shipan, the J. Ira and Nicki Harris Professor of Social Sciences, with a courtesy appointment at the Ford School, chaired Goehring's dissertation committee. 

The ProQuest Distinguished Dissertation Awards (DDA) recognize exceptional work produced by doctoral students for the high caliber of their scholarship and the significance and interest of their findings.

Each year, Rackham invites faculty to nominate outstanding dissertations produced in their programs. The nomination dossiers are read and discussed by a review panel of faculty members who identify the finalists. Then, members of the Michigan Society of Fellows (MSF) read the finalists' dissertations, review their merits, and select the winners. Ford School assistant professor Mo Torres (MPP '15) is a MSF postdoctoral scholar and a reviewer for the award. 

Below is the complete list of the winners, as well as the other honorable mentions.
