Ph.D. McMaster, 1968
My research area is experimental condensed matter physics. Currently I am interested in two areas; one associated with the physics of high Tc superconductivity and the underlying mechanisms responsible for this phenomenon. Associated with these materials, I also work on the applications of superconductivity. The other area is concerned with strong disorder and dimensionality in conductors and superconductors. Using state of the art technology we fabricate one- and two-dimensional conductors and study their properties. The relationship between dimensionality, disorder and the nature of electrical transport has fundamental underpinnings.
