The future of astronomical observations will have a heavy emphasis on the infrared. The community has made considerable investments in the James Webb Space Telescope (JWST), the successor of the Hubble Space Telescope, and the Nancy Grace Roman Space Telescope (RST), the premier telescope for the next generation of dark energy experiments. Both telescopes will observe exclusively in the infrared. My research group is now laying the groundwork for supernova observations in the near-infrared and has been gradually closing the knowledge gap in the relatively new wavelength window for each of Type Ia, Type II, and stripped-envelope supernovae. We have made some surprising discoveries in core-collapse supernovae. We have also made significant progress in identifying the origins of Type Ia supernovae, representing the first step toward constraining the variation of their properties in look-back time and reducing the associated systematic errors in distance measurements. I will summarize these results.
