He is a historian of the 20th century North American West, with particular interests in politics, cities, and environmental history.

While Silicon Valley’s high-tech companies were imagined as a clean and green alternative to industrialization, the growth, manufacturing, and economic activity introduced challenges to the region’s wildlife and its residents.
