Julia Wilker is an ancient historian focusing in the Near East in Hellenistic and Roman times, especially the history of Judaea and the Jewish diaspora from the 3rd century BCE to the 2nd century CE. She is particularly interested in cross-cultural interactions and concepts of identity and normativity in the ancient world. She has published on the Hasmonean and Herodian dynasties, Roman-Jewish relations, and Roman client kings. Her current research focuses on non-religious elites in Hellenistic and Roman Judea and the role of women in the Judean dynasties. Her second field of interest is the history of late classical Greece, in particular the rise of Macedonia and interstate relations in the period between the Peloponnesian War and the rule of Alexander.
