The experiment is simple: Apply a layer of cells to the surface of a petri dish, then scratch a line through them, down the middle. In her lab at Bucknell University, Drexel triple alumna Olivia Boerman (BS ’17, MS ’18, PhD ’22) then exposes the dish to low-intensity ultrasonic waves.

Ten hours later, the dish exposed to the ultrasonic waves has a gap less than half the size of its untreated counterpart — evidence that Boerman can accelerate the movement of cells to fill voids in a way that mimics wounds and the healing process.
