Yasunori Nomura (born 1974) is a theoretical physicist working on particle physics, quantum gravity, and cosmology.

He is a professor of physics at University of California, Berkeley, a senior faculty scientist at Lawrence Berkeley National Laboratory, a senior research scientist at Riken, and an affiliate member at Kavli Institute for the Physics and Mathematics of the Universe.

In 2017, Nomura was elected a Fellow of the American Physical Society "for pioneering contributions to a variety of areas of particle theory, including gauge unification in extra dimensions, electroweak symmetry breaking, supersymmetric models, dark matter, the multiverse, foundations of quantum mechanics, and black holes.

"[2][3] Nomura works on particle physics, quantum gravity, and cosmology.

He developed theories of grand unification in higher dimensional spacetime[4] and constructed the so-called holographic Higgs model, the first realistic model in which a composite Higgs particle arises as a pseudo-Nambu–Goldstone boson.
