I need to fill out a short history of my work experience (including volunteer). It’s not very critical for the admissions decision (they will have my CV, which is much more important), but I still need to fill it out. Anyways, I have worked as a research assistant for a professor. I was not employed by the school or the government (although I worked with people form both). My supervisor / professor was the one who paid me. In addition, I had a very similar role on my fourth-year project but was not paid. What would I put down for “employer”?
