The biennial Dissertation Colloquium brings together a select group of doctoral students from diverse institutional and disciplinary backgrounds working on dissertation topics related to the history, theory, and criticism of American architecture, urbanism, and landscape. 

The Buell Conference on the History of Architecture brings together scholars in architectural and urban history to discuss topics in architecture, urbanism, and modernity as broadly understood.

When you question the abstraction of land, you encounter soil: as a material, and as a record of the built environment. Urban soil, especially, is the subject of increasingly diverse forms of inquiries, both on the ground and in the academy. This conversation brought together practitioners of design, landscape, and anthropology in the Americas, to share notes on the unique capacity of the soil–and its associated practices such as filling–to reveal new modes of chemical kinship, new tasks for public archaeology, and new remedial building practices that have arisen on post-industrial land.

Currently he teaches at the Sam Fox School of Design and is working on a book called Thinking Through Soil for Harvard Design Press. 

Catherine Fennell teaches in the Anthropology Department and has a joint appointment with the Center for the Study of Ethnicity and Race. Her work examines how the social and material legacies of 20th-century urbanism shape the politics of social difference, collective obligation, and utopian imagination in the contemporary U.S. She has a special interest in the future of subsidized housing, and the transformation of urban built environments.
