I am a human geographer interested in agrarian change and the production of commodities, quality and value. My research asks how coffee farmers in Vietnam work with specific value chains and agricultural science to improve their livelihoods by increasing the quality and value of their coffee. This project is driven by the need for policymakers, industry and consumers to build richer understandings of rural development and changing value chains from the perspectives of producers. Theoretically, this research is grounded in political ecology, commodity studies and science and technology studies.
