- Contrast agents for magnetic resonance imaging
- Lanthanide chemistry
- Molecular imaging
The Allen laboratory explores the chemistry of the lanthanides relevant to magnetic resonance imaging (MRI) and catalysis. We are at the frontier of inorganic chemistry intersecting with organic synthesis, analytical chemistry, oncology, and biology. Three major aims in the group are to overcome critical barriers to the advanced use of lanthanide-based contrast agents for MRI; to elucidate mechanistic details of lanthanide-catalyzed organic reactions to help generate improved catalysts; and to find sustainable sources of the lanthanides. These projects will illuminate fundamental properties of lanthanides. Additionally, they are an inroad toward greatly enhancing the molecular imaging and diagnostic capabilities of MRI and increasing the quality and number of more environmentally benign catalysts for the synthesis of organic molecules.
