Thomas Gidney is a Postdoctoral Researcher in International History and Politics. He is the principal investigator for an Ambizione project funded by the Swiss National Science Foundation on Membership and international recognition from the League to the United Nations. 

Thomas completed his PhD in International History at the Graduate Institute.
