He kaiwhakaako o te ahuareka o te MIT me te kaiwhakaako awhina i LSU. He tino rongonui ia mo te waihanga i te tikanga laser interferometric ko te mahi taketake o LIGO. Ko ia te Tiamana o te Rōpū Mahi Pūtaiao COBE. He mema ia o te Fermilab Holometer whakamātautau, e whakamahi ana i te 40m laser interferometer ki te ine i nga taonga o te waahi me te waa i te tauine quantum me te whakarato i nga whakamatautau Planck-precision o te huringa holographic quantum. I te tau 2017, i whakawhiwhia a Weiss ki te Nobel Prize i roto i te Physics, me Kip Thorne me Barry Barish, "mo nga takoha nui ki te kaitirotiro LIGO me te kitenga o nga ngaru taumaha e rua e whakamahia ana e ia.
