Suburban by Nature: Silicon Valley and the Transformation of American Environmental Politics

University of Oklahoma Press, 2020

Few places symbolize the twentieth century like Silicon Valley. Stretching from the communities of San Jose to Palo Alto, the dense suburban region is home to nation’s high tech industrial corridor. In my book, I re-imagine the Silicon Valley’s history not just as symbol of post-industrialism, but as an illustrative of the consequences of the post-war period’s uneven suburban growth in shaping 20th century environmental politics, concerns over social justice, and ideas of sustainability. I complicate the now familiar story of suburbanization’s rapid transformation of post-war American cities by explaining how local activists linked social and environmental issues in creating a new form of politics. In doing so, I help place current debates over sustainability into a deeper historical context and problematize the post-war environmental movement as at once a movement of the white middle class, which gave rise to environmental and social justice movements of the latter half of the 20th century.

Machines in the Valley

Machines in the Valley seeks to use maps and immersive storytelling to demonstrate and narrate the process of landscape change in Silicon Valley between 1940 and 2010. The project combines detailed historic maps and curated visual stories to explore the racial, environmental, social, and political geographies of Silicon Valley. Inspired by geographer John Wright who argued that “places are best seen as shifting stages where the exercise of power and resistance to it vie for dominance,” Machines in the Valley explores these shifting physical and conceptual boundaries. By examining what Richard White called hybrid landscapes, I argue the interconnections between these competing idealized landscapes shaped environmental, cultural, and political identities in the Bay Area.

Digital Community Engagement: Partnering Communities with the Academy

University of Cincinnati Press, 2020

Digital Community Engagement: Partnering Communities with the Academy

Edited with Rebecca Wingo and Paul Schadewald, our edited volume brings together cutting-edge campus-community partnerships with a focus on digital projects. Through a series of case studies authored by academics and their community partners, we explore models for digital community engagement that leverages new media through reciprocal partnerships. The contributions to the volume stand at the crossroads of digital humanities, public history, and community engagement, drawing ideas, methods, and practices from various disciplines to inform our public partnerships. By highlighting these projects we hope to provide other institutions, cultural heritage organizations, universities, and communities models for successful engagement.
