I will be joining a full-time PhD program in North America in August (physical and biological sciences). While my PhD topic is my principal interest, I'm also interested in public health and health policy related challenges, and this will help me in my planned future career. I have observed that there are a number of online (part-time) MSc / MPH degrees in public health being offered by well-respected universities.
My question is:
a) Is it generally speaking permissible to enrol in another part-time program while you are pursuing a full time PhD?
b) Based on my own previous research experience, chat with my future supervisor and the members of the research group, my schedule is likely to be anywhere between 7-9 hours a day (weekends free). In principle, 20 hours of work (per week) on a part-time degree is something I should be able to do, however is this practical?
If it helps, PhD will be in experimental science (laboratory work)
Look forward to perspectives
