R. Gordon Rinderknecht is a nonresident fellow with GMF’s Democracy and Security Network. A specialist in survey design and public opinion measurement, he researches public attitudes in the United States toward the politicization of the military.

Prior to that, he completed his postdoctoral research in the Department of Digital and Computational Demography at the Max Planck Institute for Demographic Research.

Rinderknecht received his Ph.D. in sociology from the University of Maryland in 2020. His co-authored book on the situational predictors of loneliness is forthcoming with Edward Elgar Publishing.
