Now I'm in the middle phase of finishing my master degree in physics with focus on photonics. The next step I would like to pursue is actually a PhD position, but there is something that I also need to consider regarding the choice of field I am going to choose for my PhD research. The thing is I personally prefer research-based carrier, either in university or some research institutes over an employee in a company. I know that people working in a company are generally paid better than they are in universities. On the other hand, I want to earn a lot of money such that I will also be able to fund my parents and younger brother in my homecountry, in addition to living my own prosperous life. So my question is, how well are profs, lecturers, or research scientists paid in universities or laboratories? Will their salary suffice to fund their own families and parents? I would appreciate if someone can mention the typical nominal. If that's not possible, is it possible for a scientist to have a side job as another source of income, do you know someone doing that? Thanks in advance for your time.
