Description of Research 

Summary Statement of Research Interests 

Clifford Johnson's research interests are mainly concerned with the development of theoretical tools for the description of the basic fabric of Nature. He is part of the international effort to understand and describe the origin of, and the fundamental constituents (and their interactions) of the Universe. He works mainly on superstring theory, quantum gravity, gauge theory, and Mtheory, studying objects such as black holes and Dbranes, using a variety of techniques from Mathematics and Physics. Many of the same techniques can be applied to studying aspects of strongly coupled physics that are important in other experimental fields such as nuclear physics and condensed matter physics. Johnson's work in this area has led to insights into new descriptions of phenomena relevant to the quarkgluon plasma, cold atomic gases, and various quantum critical phenomena closely related to high temperature superconductors.
