I have 36 years of experience and specialize in the field of ceramics and electron microscopy with specific knowledge in the areas of phase transformations in ceramics, synthesis of ceramic powders, design and fabrications of structural ceramics and ceramic composites, geopolymers and geopolymer composites, electron microscopy and ceramic powder synthesis. I have published on such topics as zirconia transformation toughening, oxide powders syntheses and geopolymers. I have testified on reasons for hip joint failure due to insufficient chemical stabilization of zirconia ceramic.
