Research Topic: The making of a "global environmental crisis":International politics on radioactive fallout from nuclear weapons testing, 1945-63
Trained in an emerging field in the United States called environmental history, Toshi has been studying the changing relationship between the global environment and international relations. The spatial and temporal scale of global environmental changes makes it extremely difficult to recognize and deal with them. A focus of Toshi's research is to trace a historical process in which science and society interact to make such changes perceptible. Specifically, based on archival records in the United States, Great Britain, and the Soviet Union, he is exploring worldwide radioactive contamination due to nuclear weapons testing as one of the first global environmental crises. The ultimate purpose of his research is to reconstruct the rich historical experience of confronting global fallout as a guide to tackling the global environmental challenges of our time, such as climate change and loss in biodiversity.
