She is one of the curators of the exhibition What They Saved: Souvenirs and Mementos in Special Collections, on view in the Special Collections Gallery for the 2024-2025 academic year.

Before becoming a library professional, Petra earned an MA and a PhD in English from the University of Delaware, with a focus on Victorian print, visual, and material culture. From 2011-2021, she taught undergraduate courses in composition, literature, and the liberal arts at UD, Rowan University, and the Delaware College of Art and Design (DCAD). Her scholarship has been published in peer-reviewed journals such as Victorian Periodicals Review and the Journal of Victorian Culture, and most recently, in the edited collection Fashioning the Self: Identity and Style in British Culture (2023). As a graduate student, Petra was awarded DELPHI and Friends of Rockwood fellowships through CMCS and is delighted to now contribute to the Center’s work as a member of the advisory committee.

Her work centers supporting, advocating for, and participating in endeavors to build a more equitable and inclusive future for cultural heritage, decorative arts, and material culture studies, and conservation through exhibitions, programs, teaching, mentoring, and community collaboration. Catharine teaches graduate courses for the Winterthur Program, including American Interiors, Exhibitions and Interpretation, British Design History and additional independent studies and field study courses.

Kedron Thomas – Associate Professor, Department of Anthropology

Kedron Thomas is a cultural anthropologist interested in the globalization of trade and
legal frameworks, cultural and ethical dimensions of entrepreneurship and business, the
production of material culture, and the cultural politics of style and identity, race and
ethnicity, and environmental regulation. She examines these processes and practices in
the context of the global fashion industry.

She is the author of Regulating Style: Intellectual Property Law and the Business of Fashion in Guatemala (University of California Press, 2016). The book explores the neocolonial contours of the global fashion system. She argues that trademark law enforcement is an important part of how the fashion industry regulates style along the lines of race, class, gender, and geography. 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 London, San Francisco, and Portland, Oregon. Tentatively titled Sustainability in
the Making: Labor, Ethics, Ecology in the Global Fashion Industry, the book narrates
how people who work in the fashion and footwear industry are attempting to build more
environmentally sustainable and ethical supply chains. Here, her research focuses on
how evolving business strategies reflect the emergence of new and different social
identities, relationships to materials and technologies, moral sentiments and
commitments, and meanings of work and labor among white-collar employees. The
project engages conversations on material culture and materiality, ecology, and
environmentalism, the meaning and practice of sustainability, changing urban
landscapes and processes of gentrification, corporate ethics, and cultures of
contemporary capitalism.

She is the author of The Power of Objects in Eighteenth-Century British America (Chapel Hill, 2017) which was a finalist for the George Washington Prize, and received an honorable mention for the Louis Gottschalk Prize in Eighteenth-Century Studies.
