Patricia Gumport
Professor of Education
BioAs a sociologist of higher education, Dr. Gumport has focused her research and teaching on key changes in the academic landscape and organizational character of American higher education. She has studied the dynamics of academic change in several arenas — illuminating what facilitates change and what impedes it — across and within different types of colleges and universities. Extending core concerns in the sociology of knowledge and institutional theory, Dr. Gumport has analyzed how organizational, intellectual, political, economic, and professional interests redefine the content, structure, and relative legitimacy of academic fields. Specific studies include: the emergence and institutionalization of interdisciplinary fields; graduate education and professional socialization across academic disciplines; organizational restructuring and selective investment; the ascendance of industry logic in public higher education; forces that promote and inhibit academic collaboration; decision-making about appropriate organizational forms to support new ideas; and leading organizational change for optimal effectiveness with internal and external stakeholders. Her research within the United States and Europe examines how universities that are ostensibly competitors determine when and how to collaborate. Her analyses include implications for academic leaders who pursue strategic initiatives, manage environmental pressures and stakeholder interests, and seek leadership development opportunities.
