What sub-field of Physics should I pursue in graduate studies?

[\phi nix]

I am an engineering design graduate with a focus on automotive engineering. My interests tend to lie all over the place from medical image processing, medical instrumentation, robotics to non-linear dynamics, quantum mechanics, statistical physics. I am planning to go for graduate studies in the field of... well, I still haven't made up my mind yet. I am hoping that pointers from people here will help me in clearing up the confusion and learn a lot of good stuff along the way!

Physics sure is a big field, isn't it? I bet anyone could find a sub-field within physics to fall in love with!
