In the last week, I've gone from having one Master's student and one undergrad in the lab to no Master's student and three undergrads.
I haven't lost my Master's student – that would smack of carelessness – but Sandra is out of state attending a neuroethology course at Friday Harbor. She arrived without incident, and all is well so far.
I also had to recruit a student to take up an undergraduate research position I was given, who came in yesterday and will officially start next week. Then, at random, out of the blue, I had an Honor's student who walked into my office interested in a research project. And they're all taking up DNA / molecular projects, where I really have very little experience. Which is starting to feel unnerving.
