Hi all, I've got a question about PhD programs: I have a BS in Mechanical Engineering, good GPA, and have been working for 4 years since. I will have strong rec's and plan to mostly apply to Materials Science and Engineering PhD programs. I did take the pGRE this spring and scored an 850, mostly to "prove" my physics knowledge is somewhat adequate being that Imy BS is in Mech. Eng. Looking at schools to apply to, a few have more research groups in Physics departments and/or no materials science program for me to apply to. Do you think it's realistic for me to apply to some low- to mid-tier Physics (Optics or Condensed Matter) programs in cases where Materials Science isn't an option? Will I be a weaker candidate without undergrad formal training in Quantum, etc? Just trying to get a feel for which programs will take me seriously. Thanks!
