Abstract

In this interview conducted as part of a series with SLAC National Accelerator Laboratory, Uwe Bergmann recalls his life and career in spectroscopy. Bergmann discusses his early life and education in West Germany and his move to the United States to pursue a PhD at Stony Brook University and the National Synchrotron Light Source at Brookhaven National Laboratory in New York. He describes his early work on synchrotron-based Mӧssbauer spectroscopy and love of instrument-building, and his subsequent work as a post-doc at the then-new synchrotron at Grenoble, France. Bergmann goes on to describe his career as a staff scientist at the Stanford Synchrotron Radiation Lightsource at SLAC, with a significant digression on his work imaging artifacts with the SSRL facilities, including the Archimedes Palimpsest and Archaeopteryx fossils. Finally, he discusses his time as an administrator at SLAC, first as Deputy Director then Interim Director of the Linac Coherent Light Source.

Abstract

Interview with John Spence, Richard Snell Professor of Physics at Arizona State University. Spence discusses his dual role as a Director of Science at NSF and his focus on research at the intersection of biology and physics. He recounts his childhood in Australia and his undergraduate education at Queensland University. Spence describes his graduate research on plasmons at Melbourne and the opportunities that led to his postdoctoral appointment at Oxford, where he worked with Mike Whelan and David Cockayne on quantifying atom arrangements in solids. He describes his decision to join the faculty at Arizona State, and the nascent field of high-resolution electron microscopy, which compelled him to write a book on the topic. Spence discusses his work on the structure of defects in superconductors and his collaborations with Bell Labs, and he explains the significance of the LCLS to his research. He describes the BioXFEL project, his work as part of the broader community of crystallographers, and the intellectual origins of the book "Lightspeed". At the end of the interview, Spence credits Michael Crow for bringing ASU to the forefront of so much innovation in science, and he reflects on how physics has never failed to surprise him.
