Title: “The Role of Lipid Composition in Tuning Biomembrane Properties”
Each cell in our body is encapsulated and compartmentalized by lipid membranes that are only two molecules thick. These membranes must be stiff enough to form a stable boundary, yet flexible enough to readily deform and reshape as cells grow, divide, and take in nutrients. Cells meet these contradictory demands by taking advantage of the self-assembly of amphiphilic lipid molecules and the associated hierarchy of dynamic processes that spans several orders of magnitude in length scale and time scale. This seminar will highlight neutron scattering-based tools for characterizing the structural and dynamical properties of lipid bilayers and how subtle changes in lipid composition, such as mixing lipids with different tail lengths or incorporating charged lipid headgroups, can have significant effects on these properties in model biomembranes.
Elizabeth Kelley is a Staff Scientist at the National Institute of Standards and Technology (NIST). Before joining NIST, Liz received her BS from Rensselaer Polytechnic Institute and her PhD from the University of Delaware, both in Chemical Engineering. She then was a National Research Council Postdoctoral Fellow at the NIST Center for Neutron Research (NCNR) before starting her current position as an instrument scientist for the very small angle neutron scattering (VSANS) instrument. Her research focuses on linking the structure and dynamics in soft materials and biophysical systems using neutron scattering techniques.
