The always-insightful blog commenter, PhysioProf, had a terrific post yesterday on DrugMonkey about managing the various types of trainees in a research laboratory.
Some are focused on just doing interesting science. Some are working towards the goal of eventually achieving scientific independence and becoming independent PIs themselves. Some don't know why they are doing what they are doing, and may not even have ever asked themselves. Some are preparing themselves for working as scientists in industry. Some may be preparing themselves for non-scientific careers in which they make use of their scientific training: science journalism, business, law, public policy, etc. And some are just happy to have somewhere to go every day and receive a paycheck.
A discussion of each type of trainee ensues - read the whole post.
Thanks for the link!
