Not all modelling is physics, but a rather large part of modeling is. My PhD is in complex systems, and you would be surprised by the range of systems we did study. My work was on a more "traditional" field of high dimension fractal surfaces, but we had a student working on public transit models, another on ecological pattern formation, and so on.
