Hello, I have a bachelor degree in Electrical Engineering, and currently doing my masters in Computational Electromagnetics. I came to realize that my interest tends to be more on physics (or research career) rather than an engineering career. Are there possibilities to move from Engineering to applied physics when starting a PhD, or does that transition need to be made at masters level? Since in engineering, we tend to concentrate only on classical electromagnetics, I was wondering if it is possible to move to research on applications of quantum electrodynamics from an engineering background? Thank you very much. Regards
