Natalie Köhle is a historian of Chinese medicine, culture, and the body. Her research focuses on the history of humours and fluids in China. She is interested in the intersection of the history of humours, particularly phlegm, with the history of fire and the passions in Chinese medicine, and in the connections of the conceptual development of phlegm in Chinese medicine with the Āyurvedic and Greco-Islamic medical traditions. She is currently working on a book project on the history of matter in Chinese medicine, as well as on a study of changing conceptions of pores in Song medicine. Natalie is also interested in Qing Sino-Tibetan Buddhist relations, and Manchu studies. Natalie holds a PhD and MA in East Asian Studies from Harvard, and a BA in Social Anthropology and Chinese from the School of Oriental and African Studies in London.
