Our research is at the intersection of spin physics and hyperpolarization chemistry. It has applications in the study of biochemical dynamics and molecular imaging. Specifically, we drive innovation of magnetic resonance tools and techniques to break the sensitivity limits of NMR  and MRI. Our innovations enable biochemical structure elucidation with unprecedented limits of detection, and molecular imaging to spy on molecular transformations deep inside tissue. We study and control the spin dynamics of chemical hyperpolarization processes and employ quantum mechanical tricks to protect hyperpolarization from relaxation. This enables molecular tracking on hour-long timescales. With the developed technology, we enhance NMR and MRI signals by up to six orders of magnitude, which enables NMR spectroscopy and MRI imaging of small molecules at physiological concentrations to directly report on molecular function. Furthermore, we develop unconventional NMR detection schemes to probe the hyperpolarized signals. These alternative MR sensors promise ultra sensitive miniaturized and portable NMR and MRI. To propel these efforts, we work with a wide range of collaborators at NCState, Duke, Vanderbilt, Harvard, MGH, RWTH Aachen, UC Berkeley and UC San Francisco.
