uhm, I think computational physics biases about theory more. It simulates abstracted model while it don't need to practice such as loop quantum gravity...
I have searched some Computational Physics graduated program in Louisiana state university, Pennsylvania state university, Kansas state university, Illinois state university, Illinois at urban champaign. But, I don't know whether these universities educate well
computational physics is often considered as a branch of theoritical physics. Because it is a tool to adapt theories. But, someone think that it belong to experimental physics.
I want to attend graduated program about it, but I don't know what university trains it best.
