Hello, I am currently beginning my Junior year of college, and the time is coming far too soon for me to choose grad schools to apply to. My goal in life is to study all kinds of foundational physics, such as quantum foundations, quantum gravity, and string theory in order to complete Einstein's revolution and formulate a theory that will unify General Relativity and Quantum Mechanics together. I know I probably sound like some kid who's read one too many Brian Greene books, but I am convinced that this and only this is what I want to do with my life. I was actually inspired by all of Lee Smolin's books. I think his approach is the one physics needs right now, and after I graduate grad school I really, really want to join him someday at the Perimeter Institute and continue his line of research. I am asking for advice on what University to apply to that already does research in these areas so that my enrollment could better suit my needs. I'm asking this specifically because at my current school all the professors are Experimentalists, and it is getting really tiring asking questions about foundational issues and them not having an answer because they don't work in that field. About me academically, I only have a 3.3 GPA at this point. I obviously intend to study more intensely this year and the next to make up for it. I have not done any research opportunities yet, but I plan to this school year and the summer after. So, the question is: What graduate schools would you recommend for getting a PHD in physics specializing in foundational issues?
