Office: Brown Building, 29 Washington Place, Room 556

Areas of Research/Interest
Bioinorganic chemistry; study of redox potentials in electron transfer proteins; noncovalent influence on the modulation of the redox potentials

Research Description
Walters group designs nanoparticulate contrast agents for MRI image enhancement. Related research focuses on the syntheses and characterization of metal complexes that form self-assembled monolayers (SAMS) on silver for use in contrast agents and sensors.
