Jan is a fourth year Ph. D. student specializing in early medieval European history. His dissertation "Corruption in the Carolingian Empire and the Post-Carolingian Kingdoms, 800-1100" seeks to write a cultural history of justice for the ninth to eleventh century through the lense of judicial corruption. Overall, he is broadly interested in the conceptualization of justice, power, authority and their inverses in this time period, and how such concepts apply to legal, religious and political practice.

Additionally, Jan is a participant in the digital humanities project Framing the Late Antique and Early Medieval Economy. He is actively involved with the Medieval Studies Program and the Center for the Study of Late Antiquity in Princeton, having co-organized the Medieval Graduate Conference "Codes of Conduct: How to Behave in the Middle Ages" in 2016, and having run the CSLA Book Club in 2015-2016, among other organizing activities.
