Mariko Yoshida is a Ph.D. candidate in the Resources, Environment, and Development (RE&D) Program. She is interested in how everyday life is formed and maintained under ecological uncertainties. More specifically, she researches knowledge practices of precariousness through the process in which human and nonhuman entanglements emerge at local, national, and international levels, shifting and creating new forces and agents. Her doctoral dissertation investigates the trajectory of ecological risks surrounding of Pacific Oysters, questioning how unevenly distributed values and meanings have been dealt with by various communities including oyster producers, marine biologists, market authorities, distributors, and consumers. Her MA thesis (2013, Columbia University, Best Thesis Prize at the Department of Anthropology) examined the gap between Tuvaluan people and their policy-makers in responses to the long-term risks of sea-level rise as an epistemological ground. Her broader interest includes environmental anthropology’s extended engagement with political economy, Science and Technology Studies (STS), the politics of knowledge production, and material culture.
