For significant and sustained contributions in the characterization of superconducting materials, in particular:
for his pioneering work in the study of strain scaling of the pinning forc in practical superconductors,
for his insightful postulation of a unified (strain, temperature and magnetic field) scaling law,
for his discovery of the method of making practical low-resistivity electrical contacts to high-Tc oxide superconductors, which is now the prevailing contact method for HTS materials,
for authoring the book entitled "Experimental Techniques for Low Temperature Measurements", which has become the standard reference book for electrical measurements at cryogenic temperatures.
