Research Interests

Prof. John Nagle's research is in the area of biological physics. The particular systems under study are lipid bilayers, which form the structural basis of biomembranes, as well as these systems with additives pertinent to biomembranes. The Nagle group's studies focus on x-ray scattering, as well as theoretical modeling, statistical mechanical calculations and simulations, and volume measurements. The first goal is to obtain reliable data for basic structural properties and their mechanical properties. Another goal is to elucidate the interactions between bilayers. For biologically relevant fluid phase lipid bilayers, these goals involve measuring nanoscale fluctuations, for which they use synchrotron x-rays. A longer-range goal is to understand how the molecular interactions bring about the structure and the fluctuations.
