Bloomberg New is reporting that Nicholas Lemann, the dean of Columbia University’s Journalism School since 2003, is stepping down. According to CJR, Lemann will take one year off from the school and then return as a faculty member.

Lemann is the author of several books and has contributed to many different publications, including The New York Times, The New Yorker and Slate.
