Eric Walter
Senior Research Scientist
Dr. Walter is the user contact for Electron Paramagnetic Resonance (EPR). He assists EMSL users in applying both X-Band and W-Band pulsed EPR spectroscopy to diverse fields, such as geochemistry, catalysis, metalloproteins, and solid-state physics.
Research Interests
Affinity and Dynamics of Tethered Biomolecules Dr. Walter has developed a unique, continuous flow technique for determining the affinity of biomolecules for ligands. By tethering the biomolecule to a solid-phase (usually chromatography media), a column the dimensions of a typical EPR sample can be created. When placed in the EPR spectrometer, a continuous flow of ligand can be passed over the sample and the binding monitored in real time. This technique currently is being adapted to catalytic materials and a gas mobile phase. Structure and theory of the Photosystem II Oxygen Evolving Center (OEC) In collaboration with Ping Yang, Andrew Lipton, and K.V. Lakshmi, Dr. Walter is investigating the structure of the OEC, using a combination of magnetic resonance spectroscopy, cryogenic NMR, high-field EPR, and theoretical structure prediction. The research also involves using the theoretical prediction of magnetic resonance parameters in conjunction with the structure of known model compounds to refine experimental results.
