Professor Emeritus of History
I study military history and the history of technology. My focus has ranged over all of Western experience, and I have recently converted my undergraduate course in military history to a comparative world military history course. I have written about chariots in the second millennium B.C., Greek fire in medieval Byzantium, and computers and aerospace technology in the twentieth century. While I study the history of technology in general, I also focus on the ways in which technology has shaped war and war has altered technology.
