Congrats to Ryan Kowalski!
Apr. 25, 2025—Congratulations to Ryan Kowalski for successfully defending his dissertation! “Infrared Light at the Nanoscale: Confinement and Spectroscopy” Conventional optical microscopy and spectroscopy are limited by the diffraction limit, which restricts spatial resolution to approximately half the free-space wavelength of light. This constraint poses a significant barrier for the nanoscale characterization of materials and quantum systems....
