Steve Overbury FORNL

Job Titles:
  • Board, Vice President
Steve Overbury grew up in Albuquerque NM, a child of an Engineer at Sandia Laboratory who endowed him with a deep interest in science. He double majored in Chemistry and Mathematics at University of New Mexico (BS 1972), and then went on to graduate school in Chemistry at University California Berkeley, completing a PhD in Physical Chemistry (Surface Chemistry) in 1976. In 1977 he started his 39 year career at ORNL, eventually ascending to level group leader and Distinguished Research Staff before retiring in 2016. Initially, hired to work with Sheldon Datz in the area of plasma-wall interactions he developed a program in using ion scattering as a tool to probe surface structure, and gradually evolved increasingly into heterogeneous catalysis. He enthusiastically enjoyed collaborating with many researchers at ORNL as a DOE grantee in areas ranging from structure-function relations in catalysis by Au, cerium oxide and carbon; metal support interactions in catalysis; surface chemistry of oxygenates; electron-proton reactions at electrochemical interfaces, operando spectroscopy of model catalysts; soft x-ray photoemission of surface chemisorbates and redox processes in catalysts. In retirement he enjoys traveling in western US, playing music (specifically guitar), and browsing a wide range of scientific and mathematical topics.

Syd Ball

Job Titles:
  • Member of the Board
  • Research Engineer at ORNL
Syd Ball is still a part-time research engineer at ORNL, retired from full-time in 2011, re-joining in 2012. He came to ORNL straight from Yale (1957) with a B.E.E. and was transformed into a nuclear engineer by attending ORSORT and focusing on R&D of advanced reactors. He worked on HTGRs for 40 years, including the GT-MHR (gas turbine modular helium reactor) for plutonium disposition. This was a joint venture with Russia to develop means for disposition of their excess weapons-grade plutonium. Good idea! He spent several years on the ORNL nuclear desalination program, and also had many international assignments, mainly via the IAEA, with Japan, China, and South Africa. He was invited by the IAEA to Vienna in May 2022 to give the opening talk at a molten salt reactor revival meeting. At his ripe old age, he's one of the relatively few still kicking who was involved in the design, operation, and analysis of the MSRE 60 years ago. This gave him a chance to beat the drum about how the world is botching efforts to fix our energy problems, and how to do it right!
