I've been a member of the Ohio State Department of History since 1992. From July 2008 through June 2010 I held the Harold Keith Johnson Chair of Military History, a visiting professorship at the U.S. Army War College, Carlisle Barracks, Pennsylvania.
My teaching and research interests include military history, 19th century American history, insurgencies, and the problem of moral judgment in war.
My publications include The Hard Hand of War: Union Military Policy Toward Southern Civilians, 1861-1865 (Cambridge University Press, 1995); Gettysburg: A Battlefield Guide (co-authored with Brooks D. Simpson; Bison Books, 1999); The Union Must Stand: The Civil War Diary of John Quincy Adams Campbell, Fifth Iowa Volunteer Infantry (co-edited with Todd D. Miller; University of Tennessee Press, 2000); The Collapse of the Confederacy (co-edited with Brooks D. Simpson; University of Nebraska Press, 2001) Civilians in the Path of War (co-edited with Clifford J. Rogers; University of Nebraska Press, 2002); And Keep Moving On: The Virginia Campaign, May-June 1864 (University of Nebraska Press, 2002); and Shiloh: A Battlefield Guide (co-authored with Steven E. Woodworth; Bison Books, 2006).
I've received three teaching awards: the Clio Award, 1994; the Ben M. Jones Award, 1997; and the Ohio State Alumni Award for Distinguished Teaching, 1999.
