Jack Ekin is a Research Physicist at the National Institute of Standards and Technology in Boulder, where his contributions have spanned a wide range of topics in low-temperature physics, including studies of fundamental conduction processes in normal metals, electro-mechanical properties of both high- and low-Tc superconductors, and interface conduction in thin films and nanostructures. He completed a B.S. degree at the University of Michigan, conducted his early graduate work in physics at the University of Heidelberg as a Fulbright Scholar, and received M.S. and Ph.D. degrees from Cornell University. Currently, he also holds an appointment as Lecturer at the University of Colorado. He is a member of the Institute of Electrical and Electronics Engineers and a Fellow of the American Physical Society. He has published over 150 cryogenic research articles, textbook chapters, and patents, and has lectured and consulted internationally in the field of low-temperature measurements.
