(I frequently email some variant of the text in the following paragraph to my visitors and am reproducing it here for convenience. If you do want to visit me, please don't simply show up and knock on my door. Rather, make sure we have been in touch to schedule a meeting time first, or contact Sharon Kim. For interview requests and other media inquiries, contact Rika Nazem (212-998-0678) or Jessica Neville (416-516-7677) in the NYU Stern Office of Public Affairs.)
Stern office: The Kaufman Management Center is the building on the right when you face Gould Plaza, at the intersection of West 4th Street and Greene Street. Once you get past the security desk, take the elevators to the 8th floor. Turn left when you exit the elevators, walk down the corridor and through the glass door marked 8-190, veer to the right of the reception desk, walk past a set of mailboxes, then turn left around the corner into an area that looks a lot less new and shiny than the area you just walked through. I'm in 8-90, the corner office that has the door with a large printout of this on it, and adjoins a small waiting area with a big book about big data on a small table.
