This dissertation explores the institutionalization of sustainability studies within undergraduate programs in the United States, investigating its implications for interdisciplinary structure, faculty expertise, and curriculum focus. It specifically examines how sustainability studies differentiates itself from the established field of environmental studies. Employing a combination of social network analysis and bibliometric techniques, this study compares the disciplinary orientations of faculty across 60 institutions, revealing significant distinctions in academic culture. Additionally, quantitative analysis of coursework requirements for sustainability studies students highlights a broader integration of social sciences, business, and arts and humanities within the curriculum. The findings underscore the evolution of sustainability studies as a distinct academic discipline, characterized by a unique interdisciplinary approach that enhances its relevance in addressing complex environmental, social, and economic challenges.
