Educational Background

  • MS, Mechanical Engineering, Florida State University, 1994
  • BS, Mechanical Engineering, Georgia Institute of Technology, 1987

Research Interests

  • Design, fabrication and testing of high performance wire-wound magnet systems
  • to minimize system weight, installation and operational costs
  • Technology development and commercialization of devices and systems enabled by high temperature superconductors

Professional Experience

  • Present
  • Feasibility study of high-strength Bi-2223 HTS conductors for high field solenoid coils, including bending strain tests, magnetic hoop stress tests, short sample critical current measurements, technology development for layer winding, and fabrication of splice joints
  • 2012-2015
  • Developed 20 kA binary HTS/nitrogen vapor-cooled current leads for NHMFL Series-Connected Hybrid magnet
  • 2011-2012
  • HZB Hybrid and NHMFL Series-Connected Hybrid magnets developed reaction heat treatment and epoxy vacuum impregnation processes for large Nb3Sn cable-in-conduit solenoid coils
  • 2009-2011
  • PI for Phase II SBIR contracts with NASA to develop HTS conductor for spacecraft adiabatic demagnetization refrigeration system magnets and current leads
  • 2006-2009
  • PI for a Phase II SBIR contract with the US Navy to develop a quick disconnect terminal fitting for an HTS degaussing cable. Designed built and tested connector prototypes and lead effort to construct a complete HTS degaussing cable demonstration system. The effort successfully concluded with a technology transfer and license agreement to a domestic manufacturer of superconducting wire and systems
  • 2005-2008
  • PI a Phase II SBIR contract with NASA to develop conductively cooled HTS magnets to the Advanced Space Propulsion Laboratory at the NASA Johnson Space Center and the Ad Astra Rocket Company
  • 2001-2005
  • Development of 65 Tesla and 75 Tesla pulsed magnets available for scientific users at the Los Alamos National Laboratory
  • 100 Tesla pulsed magnet development program at the NHMFL
  • Repetitively pulsed coil development program in partnership with the Los Alamos National Laboratory and the Sandia National Laboratories.
  • 1994-2001
  • Mechanical design, tooling and plant equipment design, and fabrication process development for the world-record 900 MHz NMR magnet
