Stephen J. Eyles

Stephen J. Eyles is Extension Professor and Director of the Mass Spectrometry Center at UMass Amherst. His research applies hydrogen/deuterium exchange mass spectrometry to study protein dynamics and folding, with emphasis on membrane protein complexes and biomolecular interactions.

As center director, he develops analytical methods for campus researchers. Recent investigations characterize allosteric mechanisms in GPCR signaling, ER chaperone functions, and ubiquitin-proteasome regulation using advanced MS techniques.
