Juan Carlos Campuzano completed his Ph. D. degree with a thesis on infrared spectroscopy on metal surfaces under the supervision of Prof. R.G. Greenler. He developed techniques for the study of vibrations at surfaces. From 1978 to 1981, he was a postdoctoral fellow and then a Research Associate at the Donnan Laboratories, University of Liverpool, working with Prof. D.A. King, on photoemission and photoabsorption studies of various solids. Major contributions include the development of techniques for mapping Fermi surfaces from photoemission and the observation of photodesorption. In 1981, he joined the Cavendish Laboratory, University of Cambridge, as Research Associate, working on 2-dimensional phase transitions and critical phenomena. Major contributions include the demonstration that in 2-dimensional critical phenomena the fluctuations peak above the critical temperature for finite momentum transfer, the experimental demonstration of hitherto untested scaling laws, and the development of photoelectron spectromicroscopy.

In 1985 he joined the Department of Physics at the University of Illinois at Chicago, and in 1987 he also joined the Materials Science Division at Argonne National Laboratory. His major research contributions include the experimental demonstration that conformal invariance applies at the Ising critical point, the Luttinger scaling of the Fermi volume in high temperature superconductors, the discovery of a new type of singularity in the energy spectrum, momentum distribution sum rules in photoemission, the development of atomic resolution holography, the spectral function interpretation of the photoemission lineshape, the pseudogap in the energy spectrum of underdoped superconductors, the discovery of Fermi arcs, the study of spontaneous time reversal symmetry breaking in the new high temperature superconductors, new methodologies for extracting response functions not previously obtainable from photoelectron spectroscopy, etc.
