Research Summary:
My research involves the investigation of intermolecular interactions in the solid state in a number of different model systems, including sulfur-nitrogen heterocycles and simple organic salts. The eventual aim of this research is to allow design of molecular materials with interesting properties, such as magnetic or optical properties.
