Research Interests

Stephanie Tristram-Nagle actively performs research into lipid membrane structure, properties and thermodynamics. Her lab explores the structure of biological phospholipids, lipid/peptide and lipid/cholesterol mixtures using oriented samples on substrates or large unilamellar vesicles using X-ray diffuse scattering with a Xenocs Xeuss SAXS/WAXS instrument here at 好色先生TV, and with synchrotron radiation at the Cornell High Energy Synchrotron Source (CHESS). Her current focus is on the interaction of antimicrobial peptides with bacterial membrane mimics. The X-ray data yield not only structure, such as lipid area and membrane thickness, but also the bending and compression moduli of the membranes. Tristram-Nagle collaborates with MD simulators to compare experimental with simulated results. Her lab also measures lipid volumes with an Anton-Paar 5000M densitometer and D2O-H2O mixtures.
