CURRENT RESEARCH
Understanding the atomic and molecular level structure of materials is of fundamental interest in chemistry and materials science. By understanding the structure of materials, a greater understanding of their functions can be developed. Nuclear magnetic resonance (NMR) spectroscopy, a close cousin to magnetic resonance imaging (MRI) that many are familiar with in a medical context, is a powerful tool for elucidating the structural features of materials. I am particular interested in exploring the ability of NMR spectroscopy to be used for crystallography – the determination of crystal structures – by which the atomic arrangement of materials can be determined.
