Heloisa Nunes Bordallo

Associate Professor

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.
