My major areas of interest are Jewish thought and the reception history of biblical symbols.

In the area of Jewish thought, I cut my mental teeth on German Jewish intellectuals and Continental philosophers Hermann Cohen (1842-1918), Martin Buber (1873-1965), Franz Rosenzweig (1886-1929), and Leo Strauss (1899-1973). A volume with essays on Jewish thought is forthcoming in German (Jüdische Religionsphilosophie als Apologie des Mosaismus, under contract with Mohr Siebeck, Tübingen).

In the area of the biblical religious symbols and their afterlives in our western religions as well as in the contemporary world, I am currently focusing on the holy city of Jerusalem. (See I am currently completing a Brief History of Jerusalem for Wiley-Blackwell, where I attempt to answer the question how an ordinary royal city of the ancient southern Levant became the holy city of Jews, Christians, and Muslims.
