Masahiro Morii
Professor of Physics
PhD 1994, University of Tokyo
Masahiro Morii is an experimental physicist working on
studies of elementary particles and their interactions. He
is currently involved in the LUX
Dark Matter Experiment, which will be installed
in the Sanford Underground Laboratory at Homestake, SD. The
experiment uses 300 kg of liquid xenon to detect the Dark
Matter - an invisible form of matter which make up 4/5 of
the mass of the Universe.
Prof. Morii is also involved in the ATLAS
experiment at the Large Hadron Collider at
CERN. The experiment is anticipated to uncover the origin
of the electroweak symmetry breaking, and has a great potential
for discovering new physics beyond the Standard Model.
