He received his Ph.D. in History from Yale University in 2017 and recently taught at Stanford University. Gross specializes in Ancient Jewish and Christian history, currently concentrating on Jews and Syriac Christians living under Sasanian Persian and early Arab-Muslim rule. He is also interested in the co-formation of Judaism and Christianity in antiquity. One of his current projects is to study Jewish and Syriac Christian historiography not as unproblematic accounts of the past, but as reflections of their authors' present imperial context. He recently co-authored the book The 'History of the Slave of Christ': From Jewish Child to Christian Martyr.
