I am Professor of Art History at California State University, Chico. I have written Maps and Monsters in Medieval England (Routledge, 2006; paperback 2008), co-written with Susan Kim Inconceivable Beasts: The Wonders of the East in the Beowulf Manuscript (ACMRS, 2013), and a number of articles on the subject of monstrosity and marginality in the Middle Ages.
I coedited with Peter Dendle a Research Companion to Monsters and the Monstrous (Ashgate, 2012), and am the president of MEARCSTAPA (Monsters: the Experimental Association for the Research of Cryptozoology through Scholarly Theory And Practical Application), accidentally founded at Kalamazoo in 2008 to create a home for walkers in the margins of academia. I am co-director of Virtual Mappa, with Martin Foys.
I am now at work on a book about the Franks Casket, and another about images of Jews on medieval world maps. I am an active (and founding) member of the Material Collective, and a regular contributor to the MC group blog.
