Funding for Public Health Doctorate (DrPH)

[BillyRubin]

I'm looking at doctoral programs in Public Health programs, and was wondering how often students are able to get funding for their doctoral work. Specifically I am looking at the CUNY Graduate Center and Columbia. I understand that funding is scarce, particularly at public schools, but I am hoping that there is some funding available to cover tuition costs. Does anyone know about DrPH funding at these schools or in general?
