My research interests are in lipid membrane structure, thermodynamics and fluctuations. Our Biophysics laboratory explores the structure of biomimetic membranes containing phospholipids, peptides and cholesterol mixtures using oriented samples on substrates and unoriented multilamellar or large unilamellar vesicles.  We use X-ray diffraction with a Rigaku rotating anode and CCD detector here at CMU, and synchrotron radiation at the Cornell High Energy Synchrotron Source to obtain diffuse scattering data that yields not only structure but also elastic parameters. Our recent experiments also use neutron scattering.  Another technique is differential scanning calorimetry to measure specific heat changes during phase transitions of aqueous dispersions of phospholipids in the form of MLVs. The fourth technique which yields structural information about the lipid volume as a function of temperature is neutral flotation using D2O-H2O mixtures and our DMA5000M vibrating tube densimeter. In addition, we use circular dichroism (CD) to determine the secondary structure of peptides as they interact with lipid membranes.  The current focus is on the interaction of antimicrobial peptides with lipid model membranes.
