I am a Ph.D. student in mechanical engineering and almost done with my thesis. My bachelors was in Physics. Although the initial research plan fit into mechanical engineering - vibrations, thanks to the freedom my supervisor gave me, I gradually moved into dynamical systems theory, complex systems and networks, computing, neural networks, optimization, etc. Looking at my thesis, it is a stretch to call myself a Ph.D. in mechanical engineering. It would make more sense to obtain a Ph.D. in Physics or Applied Mathematics rather than mechanical engineering
Has anyone faced such a situation? Can I request the university for this? If yes, how would I go about this?
