My teaching, research and writing is informed by the discourse of history and viewed through an interdisciplinary lens. In the classroom, I challenge students to raise questions as the necessary first step to their critical reading and analysis of primary and secondary sources. Writing assignments reinforce this approach by requiring students to formulate thesis statements with an argumentative edge and to present evidence to support the thesis. My courses emphasize the central issues and questions that shape U.S. culture and help students recognize and understand the complexities of causation, continuity, and change. As much as appropriate, I use fiction, autobiographies, founding narratives, architecture, painting, and facets of popular culture to provide a holistic and integrated view of the past. In order to engage students, I use a variety of discussion formats, ranging from the basic Q and A to student-centered groups.
