David S. Cafiso

David S. Cafiso is a Professor in the Department of Molecular Physiology and Biological Physics at the University of Virginia. His research focuses on the molecular mechanisms of membrane transport and cell signaling, utilizing advanced techniques such as EPR spectroscopy, high-resolution NMR, and solid-state NMR. He has made significant contributions to understanding membrane protein structure and function, particularly in relation to synaptic vesicle exocytosis and bacterial nutrient transport.

• Education: AB, PhD in Biophysics from the University of California, Berkeley; Postdoctoral training at UC Berkeley and Stanford University

His research interests span Biochemistry, Biophysics, Structural Biology, Neuroscience, and Microbiology. Recent work highlights conformational dynamics in membrane proteins, lipid-protein interactions, and the role of electrostatics in signaling. Publications emphasize PIP2 regulation, C2 domain function, and TonB-dependent transport systems, with applications in both bacterial physiology and neurosecretion.

Professor Cafiso's laboratory investigates two primary areas: (1) Membrane protein attachment mechanisms critical for cell signaling, and (2) Solute transport across lipid bilayers in gram-negative bacteria. His studies often integrate biochemical, structural, and biophysical approaches to probe dynamic processes in membrane biology.
