There’s a great post up at ProfSnarky’s, giving advice to undergrads who have just gotten a job with a prof. It’s full of some really good advice, and if you’re an undergrad who wants to do research, I definitely suggest you check it out!
But I also thought I would add some of my own thoughts here. Because if you work for someone in biomed at a big uni, the odds are, you’re not working for that big Prof. Nope, you work for that big Prof in name only and see them once or twice a semester. In reality? You work for the postdocs and grad students in the lab. In the day to day, the undergrads in my lab work for me.
