David Sauer is a biophysicist focusing on the structure and function of membrane channels and transporters. As group leader at the University of Oxford since 2021, he has been studying the structure and function of membrane proteins for 16 years. David completed his graduate degree studying potassium channel structure and ion selectivity at the University of Texas Southwestern Medical Center. This was followed by postdoctoral training at New York University School of Medicine. There he described the structure, transport mechanism, and chemical inhibition of SLC13/DASS membrane transporters.
