I am in computer science (CS). Is it possible to volunteer to do research in a CS group at a university during summers or part-time after I have already completed my bachelor's degree in CS?
I want to get some more research experience, but my understanding is that "undergrad" research work must legally be paid for and that I am basically not going to find opportunities like I am describing. Is this assumption correct?
If not, how do I go about finding these opportunities, just cold-emailing faculty? What are some other ways to get research experience after graduating in CS other than doing a master's?
