I am a medical student working in a lab. It's a pretty good lab, but I'm wondering if it's normal/expected for students to get paid for work done in a lab. I've been working for about 10hrs per week for almost a year (full time in the summer). I am otherwise happy with the lab, I will be getting a publication soon (not first author, but this is basic science so any pub is good), and my poster won an award at a conference. So I don't want to mess with a good thing, but I was wondering if it would be appropriate to ask for pay. When I first started working here my boss's boss mentioned the possibility of paying me, but nothing was said about it again and I felt uncomfortable following up.
