During much of her undergraduate career, she played tenor banjo in a jazz combo. Like many students of math and science, she was attracted to music theory and its mathematical structure, and she had a natural talent for playing. She and a group of friends played gigs frequently at local cafés and other venues down the hill from Cornell in the town of Ithaca. (In fact, getting down the steep hill was often a challenge, especially in the icy months of winter. ) As her student years passed and her studies in science intensified, she found that the demands of her coursework began to take up so much of her time that one evening during a gig she felt a sudden jolt in the midst of playing a piece.
