Improving Art Conservation and Clinical Diagnosis Using Novel Molecular Imaging

Warren S. Warren, PhD
James B. Duke Professor of Chemistry, Radiology, Biomedical Engineering and Physics
Director, Center for Molecular and Biomolecular Imaging

Dr. Warren’s research interests are in molecular imaging and molecular spectroscopy, primarily focusing on magnetic resonance and optics. Molecular imaging, the use of chemical signatures to image a function, promises to revolutionize both diagnosis and treatment of diseases such as cancer. In magnetic resonance, new “hyperpolarization” technologies can turn almost any chemical into an MRI "light bulb" to highlight abnormalities. Dr.Warren’s lab has found ways to make the MRI signal last much longer, and in optics, developed laser technologies that target specific molecules (hemoglobin in blood, melanins in skin cancer), and shown that these methods improve diagnosis. The Warren lab has also used the same methods to do nondestructive imaging of Renaissance paintings by looking directly at the structure of the paint layers, and thus learn about technique, retouching, and possible degradation mechanisms, to infer the artist’s original colors and intent.
