Katie McCormick received her PhD from University of Colorado in 2019. While there, she studied the quantum motion of a single atom trapped by electric fields. She learned how to control its motion and how to use this to make very precise measurements of the electric fields near the atom. Following the PhD, she moved to Seattle for a postdoctoral position at University of Washington. Here, she has moved on from studying just one atom to studying thousands to millions of atoms. She is trying to make ytterbium-lithium molecules from ultracold clouds of these two types of atoms.
