I got the Kinesiology job! I'm starting in two weeks.
On my third interview today, they showed me four labs. One is being used for a blood-flow study for the European Space Agency and NASA! My involvement with that lab is likely very low. But still, very cool. Another lab has servo-controlled back-joints, to test joint stress through regular, repeated motion. It's likely I'll be working on that.
What a load off my mind. The timing was... weird, but hey, I'll take it.
This will take some time to sink in, I think.
