Research Interests

My research interests relate to the crystallography, solid-state chemistry and solid-state physics of inorganic compounds. My research is focused on crystal chemistry, and crystal-structure - property relations in functional inorganic materials; a unifying theme in almost every aspect of my work is the compositional tuning of the properties of extended solids through solid solution.
