Clifford V. Johnson

Clifford V. Johnson is a Professor in the Department of Physics and Astronomy at the University of Southern California, where he develops theoretical tools for describing nature's fundamental constituents and their interactions across all scales—from elementary particles to cosmology.

His research specializes in string theory, quantum gravity, and quantum field theory, with direct applications to quarks, black holes, and the universe's structure. Johnson actively promotes public science literacy through articles in SEED, Discover, and New Scientist; media consulting; and contributions to programs like The Universe on the History Channel. He also maintains the blog Asymptotia, exploring intersections of science, arts, gardening, and food culture.
