John Constance studied Integrative Social Science with a focus on politics, economics, and ethics at the Technical University of Kaiserslautern. His master thesis at the Chair for International Relations was on the subject of the democratic control of U.S. military intervention policy under President Barack Obama.
Simultaneously he worked as a civilian employee for the Army and Air Force Exchange Service and the Defense Commissary Agency of the U.S. Department of Defense at Ramstein Air Base. In this function, he was able to gain a comprehensive insight into the peculiarities of American culture, the fundamental American way of life, and the exceptional living conditions of U.S. service members stationed in Rhineland-Palatinate in particular.
His research interests are U.S. foreign and security policy, transatlantic relations, as well as societal studies in the historical context.
