His historical research focuses on two topics in mid to late nineteenth-century America and Britain: the history of medical imaging, especially the history of early American roentgenology, and the history of pain without lesion. During the Visiting Fellowship, he worked on comparing the beliefs, attitudes and practices of leading British neurologists with those of their American counterparts. Details and podcasts from his public workshop 'History of Pain without Lesion in the mid to late Nineteenth Century' held in May 2012 can be found here.
