Structure, function, and dynamics of macromolecular assemblies
The Murray Lab is interested in the physical properties of condensed phases of biological macromolecules that assemble into membraneless organelles and pathogenic aggregates in living cells and tissues. We use nuclear magnetic resonance, fluorescence, electron microscopy, calorimetry, and other tools of physical chemistry to examine the structural, thermodynamic, and kinetic properties of these assemblies. Our results are important for understanding biological processes in RNA metabolism and aggregation pathways in neurodegenerative diseases. In another avenue of research, we collaborate with the Joint BioEnergy Institute at the Berkeley Lab, where we use spectroscopy to examine bioengineered plants for use as novel biofuels.
