Research Interests

My main research interests are in inorganic microstructures and the relationship between microstructure and mechanical or electronic properties. Current research interests are  (i) devitrite, Na2Ca3Si6O16, (ii) the joining of ceramic materials, (iii) microstructure-property relationships in electronic ceramics such as lead-free piezoelectric materials and zinc-oxide-based varistor materials, (iv) the structure of grain boundaries and interphase boundaries in ceramic materials, (v) the microstructure of crystalline glazes, (vi) twinning in complex crystals and (vii) tensor algebra of the elastic behaviour of anisotropic crystalline materials.
