With the generous support of the Gates Cambridge Trust, I am starting my PhD in the History and Philosophy of Science. My doctoral research concentrates on mid-twentieth-century wet brain collections and material cultures in neurosciences, psychiatry, and neurology, illustrating the interdisciplinary and collaborative nature of brain-related research; the transnational context of locally produced knowledge; and the consequences of spatial arrangements of basic research, clinical practice, and industry-led studies. It aims to provide a desperately needed historical perspective for mid-twentieth-century medical collections in neuropathology, many of which have been dissolved, archived as museum collections, or re-investigated with contemporary methods in the last two decades.
