Assistant Professor

Specialty Areas:

Single particle cryo-electron microscopy (cryoEM); membrane protein biochemistry; pharmacology; and site-directed fluorescent labeling techniques

Research Focus:

Dr. Fay’s work seeks to gain atomic insights into the biochemical function of ion channels and membrane proteins in airway epithelium. His research utilizes various techniques to interrogate protein structure and dynamics to provide fundamental insights into the molecular underpinnings of how these proteins function in both healthy and diseased states.
