The unifying theme of my research has been to understand the effects of structural changes on the physical properties principally those governing dynamics in, and induced around, a material. The sequence of topics I worked on evolved from luminescent impurities in ionic crystals to other classes of materials; ferroelectrics, colossal magnetoresistance, molecular magnets, cement paste, clays, and then to systems of biological significance. As a consequence of this development of scientific interest, I have been trained in a broad range of experimental and computational techniques, starting with optical spectroscopy and proceeding to Raman, infrared, elastic and inelastic neutron scattering, X-rays and synchrotron radiation.
I have sought to develop links to strong collaborators at the international level and have being engaged on promoting neutron scattering as a technique that possesses the ability to answer important questions to physicists, chemists, material scientists, and biologists.
