Kedron Thomas – Associate Professor, Department of Anthropology

Kedron Thomas, Anthropology.

Kedron Thomas, Ph.D., is an associate professor in the Department of Anthropology at the University of Delaware. She is a cultural anthropologist with expertise in textiles, clothing, and fashion, especially the diversity of what people wear and how it is made. Her first book, Regulating Style: Intellectual Property Law and the Business of Fashion in Guatemala (University of California Press, 2016), is based on long-term research with Indigenous Maya apparel manufacturers who make clothing that features unauthorized reproductions of fashion brands. She examines the rise of “knockoff” fashion in Central America amidst the politics of race and indigeneity, efforts by the Guatemalan state and international institutions to promote entrepreneurship and national development after nearly four decades of armed conflict, and the globalization of intellectual property regimes that criminalize practices of brand “piracy.” Her current book project describes the politics of environmental sustainability and labor rights from the perspectives of designers, marketers, and brand and supply chain managers at fashion and footwear firms in cities across the US and UK. Tentatively titled, Sustainability in the Making: Labor, Ethics, and Ecology in the Global Fashion Industry, the book narrates how fashion professionals are attempting to build more environmentally sustainable and ethical supply chains.

Thomas earned a Ph.D. in social anthropology from Harvard University in 2012. Before joining the University of Delaware, she was associate professor of anthropology at Washington University in St. Louis.
