Before joining the Primary Source staff, Susan was a professor of History at Regis College in Weston, Massachusetts, where she taught courses in gender and global studies and all aspects of U.S. history. One of her favorite responsibilities was supervising undergraduate teacher-candidates in both elementary and secondary education.

Susan is the author of books and articles on topics that include immigration and race, international relations, and gender, war and peace movements. Her most recent publication is Entangling Alliances: Foreign War Brides and American Soldiers in the Twentieth Century (March 2010, New York University Press).

Another professional interest is oral history and theatre. She collaborated on a teaching project that became "Testimonio," a play based on oral interviews about women's experience of political repression in Central America.

Susan holds a Ph.D. in U.S. History from New York University.
