You know, I've been asked multiple times about my research and publications in interviews so far. They will give you a chance to talk about it. You can also make it a point to bring it up because it is an important one. ERAS does not allow an application to be changed once it is submitted. Only the profile part can be changed. That's what sux about it. As far as the interviews you may have completed so far, you can always try to find a way to bring it up in the Thank you notes you send out. Like "In reference to our conversation concerning blah, blah...." Does this help a bit??
