I teach U.S. West, Pacific Northwest, and public history courses at Portland State University. My most recent book was released in summer 2018. In Defense of Wyam: Indigenous-White Alliances and the Struggle for Celilo Village (University of Washington Press) presents a remarkable alliance across the opposed Native and settler-descended groups, chronicling how the lives of two women leaders converged in a shared struggle to protect the Indian homes of Celilo Village. Other publications include Death of Celilo (University of Washington Press, 2005) and Nature’s Northwest: The North Pacific Slope in the Twentieth Century (with William Robbins, University of Arizona Press, 2011).  

Check out this podcast interview I did with the PSU students who run "Footnotes," interviews with faculty, students, and local historians. We talked about how I became an historian, public history, and my research.  

My public history work includes conducting oral histories for the U.S. Forest Service, Chinook Indian Nation, and Oregon National Guard, historic resource studies for the National Park Service, and consulting with Northwest museums. From 2006-2011, I directed the Center for Columbia River History (CCRH), a public history consortium located on the grounds of Fort Vancouver, a National Park Service site, which included Portland State University, Washington State University Vancouver and the Washington State Historical Society.
