Call the Residency Coordinator at Emory or you can email the PD... You can get the contact information from their website. The application requirements are pretty much the same as everywhere else, CV, LOR, NDBE, completed application, transcripts, and proof of liability... Apply well in advance of your proposed dates because you'll need some time to arrange your own living accommodations. At Grady you'll extract a lot of teeth, and see some impressive trauma on call nights. The Emory Clinic doesnt offer much for you to do besides observational learning. However I saw a lot and learned alot while I was there. Hopefully you'll feel the same way. Also be prepared to be pimped. And there is an application fee payable to Emory University.
Best of luck
