Louise Nelson Dyble specializes in the history of technology, infrastructure and the built environment, and metropolitan government and governance. Her book, Paying the Toll: Local Power, Regional Politics, and the Golden Gate Bridge (2009), traces the history of the bridge in the context of land-use politics, development, and planning--and also examines the inner workings of the bridge's unpopular administration. Her ongoing research includes a study of road and highway financing in the United States with a focus on turnpikes and the politics of public enterprise in the late twentieth century. Dyble earned her PhD at the University of California, Berkeley, and has taught and conducted research at Caltech and the University of Southern California. She worked for two years as the Research Director of the Keston Institute for Public Finance and Infrastructure Policy. Dyble is currently a J.D. candidate the the University of California, Berkeley School of Law.
