The existence of dark matter has been indicated in many astrophysical phenomena, but the nature of dark matter still remains a great mystery. Complementary dark matter searches with different detection methods are crucial to illuminate the nature and the origin of dark matter. In this talk, I will be presenting my research on both the SuperCDMS (direct dark matter search) and the GAPS (indirect dark matter search) experiments as well as the scientific roles of the projects in the dark matter search. While SuperCDMS measures the dark matter scattering within the detector, GAPS focuses on low-energy antiprotons and antideuterons produced by dark matter annihilation and decay in the Galactic halo. Both projects are funded for a science run/flight and will begin taking data in 2020. I will also be introducing a new project/concept, GRAMS (gamma-ray and antimatter survey) that I have been developing over the past year. GRAMS is the first experiment aiming for both MeV gamma-ray observation and antimatter-based dark matter search using a LAr-TPC detector. Through GRAMS, we can explore astrophysical objects in the MeV energy domain (“MeV gap”) while pursuing dark matter.
