Siyen Fei received her PhD from Stanford University in 2004. She has been teaching Chinese history at University of Pennsylvania since then. Her work to date is primarily concerned with the political and cultural activism of sixteenth- and early seventeenth-century Ming dynasty (1368-1644). Examining the action of wide-ranging historical actors—women, urbanites, and border residents—she engages and expands the new scholarly paradigm of “defiant late Ming energy” that re-visions a society formerly considered submissive to an all-powerful imperium. At the MPIWG, she is working on a project on cross border captivity in collaboration with the LoGart team.
