Kayleen is obsessed with the brain. After majoring in neuroscience at Vanderbilt University, she went straight to a PhD program in neuroscience at the University of Iowa. She currently studies how our brains process speech. She measures electrical changes produced by the brain to understand how the gender of a person talking influences how we hear their speech. Outside the lab, she works to get others excited about science and occasionally plays the bassoon.
