I am a political ecologist and nature-society geographer who examines agri-food systems through the lens of knowledge production and circulation. Broadly, my research focuses on how the movement of knowledge impacts responses to new and novel forms of life including pests, pathogens, and genetically-modified organisms.


My dissertation examines shifting knowledge systems following the outbreak and spread of banana Xanthomonas wilt in western Uganda. This deadly plant disease has quickly spread across the country mobilizing an unprecedented response. My research asks what are the outcomes of this shift? Whose knowledge is valued, and what counts as expertise? Finally, how do knowledge systems translate into changes in the physical and political landscape in Uganda?
