Biophysical Chemistry of Lipids and Membrane Proteins

Research in the Baiz group focuses on describing the molecular mechanisms that determine the structure and dynamics of membrane-associated peptides and proteins. We investigate the mechanisms of protein folding, self-assembly, and function with particular interest in understanding the role of heterogeneous environments in lipid membranes. Secondary structure, folding mechanisms, and kinetics are the result of a highly-specific thermodynamic balance between hydrophobic contacts, electrostatics, and solvent-exposure, and for membrane proteins, the environment significantly increases the diversity and complexity of these interactions.

We address these challenging topics by developing new tools based on time-resolved infrared spectroscopy and microscopy. More specifically, we design new applications of two-dimensional infrared spectroscopy, a technique that measures global protein structure, backbone flexibility, and solvent exposure with sub-picosecond time resolution. Experiments are supported by quantum-mechanical models of vibrational spectroscopy combined with extensive structure-based computer simulations.
