Mary Corbin Sies is an Associate Professor in the Department of American Studies, University of Maryland, College Park, and an Affiliate of the Women's Studies Department, the African American Studies Department, the Graduate Program in Historic Preservation, and the Consortium on Race, Gender, and Ethnicity. She is interested in theorizing and studying issues of race, gender, class, space, and the domestic built environment and processes of community-building. She is actively rethinking the theory and practice of historic preservation to center on the tangible and intangible heritage of marginalized subgroups in the United States and on community-engaged scholarship. She collaborates with the Lakeland Community Heritage Project to document and interpret the history of Lakeland, a nationally significant African American suburb located near the University of Maryland campus. Professor Sies promotes advocacy and social justice in her scholarship and her teaching.
