Taylor Oldfather, a doctoral student working in Auburn's Biomechanical Engineering Lab isn't on Twitter. She's barely on Facebook. Before this week, she'd never even heard of TikTok. But after this week? She just might sign up. 

There's just so much data to work with. When first approached with the idea to map the moves of the latest social media dance challenge via motion capture, Oldfather wasn't exactly expecting to find anything scientifically interesting. It was supposed to be mostly for fun. But when lab workers suited students with reflective markers, cranked up the music, and hit record, she did a double take.
