In collaboration with his father, Luis Alvarez, he published a groundbreaking study in 1980 that suggested a meteorite impact caused the mass extinction at the Cretaceous-Paleogene boundary. His hypothesis was initially met with skepticism but later gained substantial support after the discovery of the Chicxulub crater in Mexico.
