My US company offered me the prospect of doing my PhD (in public health, public policy, international development or something similar) at a European university while retaining my employment. They would also pay for the PhD. My thesis would be based on a research project I was already going to pursue in my work. I already have a Masters in Economics. Would a university be okay if I only worked out of the university for the first and the 2nd and 3rd year was finishing my research in the USA? Thanks!
