The fraction of supernovae missed in optical surveys due to extinction and intrinsic faintness is as much as 50%. We have pioneered the use of Laser Guide Star Adaptive Optics on Gemini and Keck to reveal a previously hidden population of core-collapse supernovae in Luminous Infra-Red Galaxies (LIRGs). To measure the fraction of heavily obscured supernovae, high-precision infrared observations are essential. We are undertaking the SUNBIRD (Supernovae UNmasked By Infra-Red Detection) project with Keck and Subaru to monitor 36 LIRGs over semesters 2016A-2018B, and increase the sample of obscured supernovae by at least a factor of 3. The data on the LIRGs themselves is also of immense value for understanding the dusty, starbursting galaxies at low and at high redshift.
