Led the study and built the Juno Waves instrument

NASA's Juno spacecraft crossed Jupiter's bow shock twice on December 10 and 11, 2024, and recorded something no spacecraft had caught at any planet's shock front: an electric-field wave ringing at several frequencies at once. The main tone sat near 5,600 hertz, with overtones at roughly double and triple that pitch.
