Her research and teaching interests bridge the fields of social and political history and focus, in particular, on collective action, state building, reform movements, and politics.

Her most recent book the War on Alcohol: Prohibition and the Rise of the American State (W.W. Norton, 2016) has won wide acclaim for excavating the significant but neglected state-building legacies of national Prohibition.
