Bio

Research Interests:

Beth joined Oak Ridge National Laboratory (ORNL) to work on the development of functional materials and coatings. This work includes the development of alternative forming techniques for oxygen and NOx sensors, solid oxide fuel cells, gas separation devices, and corrosion resistant coatings.

Education:

  • M.S., Material Science and Engineering, University of California, Los-Angeles, California, 2000
  • B.S., Ceramic Engineering, University of Illinois, Champaign-Urbana, Illinois, 1988

Research Experience:

Beth has over 13 years of experience in the area of ceramic processing. Prior to joining ORNL, Beth worked at Pacific Northwest National Laboratory (PNNL) for 8 years and Garrett Ceramic Components for 4 years. At PNNL, her research activities included the extrusion of tubular supports for oxygen separation membranes, slip casting of electrochemical cells, the development of compression molding technology to fabricate complex planar components for fuel cells and oxygen generators, processing of resorbable and implantable bio-ceramic devices, synthesis and processing of nanoparticles, fabrication of catalyst supports and membranes, processing of biomaterials, the development of a resorbable bone filler and ceramic net shape forming techniques. At Garrett Ceramic Components, Beth evaluated gelcasting of silicon nitride components for use in automotive and aerospace applications. In addition, she worked within a team to develop processing methods for net shape fabrication of complex shapes and to understand the rheology of suspensions for slip casting. Other activities included compositional development, high-temperature mechanical property evaluation, and corrosion studies of silicon nitride.

Professional Societies:

  • American Ceramic Society
