Understanding the formation and quenching of massive quiescent galaxies at cosmic noon (z~2) remains a major problem in galaxy formation theory. While clues to their formation will be imprinted on the stellar populations in their inner cores, such analyses are beyond the capabilities of current technology. Here, we present some preliminary results from a unique upcoming survey leveraging the Hubble Space Telescope WFC3/G141 grism spectroscopy and ALMA dust continuum imaging of a unique sample of gravitationally lensed massive quiescent galaxies from z = 1.6 to 3. The boost in spatial resolution and signal that strong gravitational lensing affords gives us the rare opportunity to perform spatially resolved age measurements at 0.5 kpc resolution and improved sensitivity to measure their gas content.
