Cohen is Khedouri A. Zilkha Professor Emeritus of Jewish Civilization in the Near East and Professor Emeritus of Near Eastern Studies at Princeton University. He is a scholar of the history of Jews in the Middle Ages under Islam. His research relies greatly on documents from the Cairo Geniza. From 1985 until his retirement in 2013, Cohen led the Princeton Geniza Lab, which aims to make the Cairo Geniza's corpus available and searchable online. As of 2023, the database contains 400,000 documents. The project was headquartered at the Shelomo Dov Goitein Geniza Research Lab, where many of Goitein's books and notes are stored, but is now separate.
