Peter Johnson is an internationally recognized leader in superconductivity and photoelectron spectroscopy. He joined the Brookhaven National Laboratory in 1982 and rose through the ranks to become a senior physicist in 2000, and Associate Chair of Brookhaven's Physics Department from 2003 to 2006. Peter Johnson was appointed Deputy Chair of the Condensed Matter Physics and Materials Science Department upon its founding in April 2006. From 2007 to 2015 he was the Chair of the Department. He also leads the department's electron spectroscopy research group. His research focuses on materials in which electrons are confined to two dimensions, rather than the usual three dimensions. Two-dimensional materials include the surfaces of metals, where catalytic reactions take place, magnetic multilayers, consisting of alternating layers of thin films of magnetic and nonmagnetic materials, and high-temperature superconductors.

Peter Johnson is a member of Comscope since its foundation. His research group validates the theoretical spectroscopic predictions of the Comsuite by photoelectron spectroscopic measurements, in which an electron absorbs energy from light and is then ejected from the material under study, thus revealing information about its properties.

Johnson received Brookhaven Lab's Science and Technology Award in 2001 and the American Physical Society's Oliver E. Buckley Prize in 2011. He is the author of 185 peer-reviewed scientific papers.
