Hi suilove. Since I'm just beginning this merry-go-round myself, I can't really offer much advice, but I thought I'd identify myself in response to your call for comrades. I'm looking at PhDs for Modern/Contemporary western art, possibly considering a curatorial focus where available (but slightly suspicious of that, as well). Think I'm looking at the NYU IFA, CUNY Grad Center, Harvard, Princeton, Bryn Mawr, U. Chicago. Unambitious, you could say.
Where are you located, may I ask? There's a really neat-looking symposium on contemporary Chinese art at MoMA next month.
