I am an Associate Professor at the History Department of Miami University. I obtained both my Masters degree and PhD degree from University of Iowa. I am regularly teaching courses in Medieval Europe and World Histories, and occasionally teaching courses relating to Chinese civilization. I have published some entries in various encyclopedias, and articles in academic journals in English and Chinese. For the past few years, I have been invited to teach in Northeast Normal University, Changchun, China, helping Chinese scholars and graduate students with understanding World History scholarships in the contemporary West.
