Research topic: 

Receptor-ligand interactions and conformational transitions using computational and experimental approaches

Our lab is focused on understanding the molecular mechanisms of how multisubunit protein assemblies function. We are particularly interested in elucidating the structural thermodynamics that govern ligand binding, subunit assembly, and allosteric control of neuroreceptors such as ionotropic glutamate receptors (iGluRs). iGluRs are ligand-gated ion channels that mediate the majority of excitatory synaptic transmission in the central nervous system. iGluRs are important in synaptic plasticity, which underlies learning and memory, and these receptors have been implicated in a number of neurological disorders and diseases. Our approach relies on a combination of structural, biochemical, biophysical, and computational methods to define the architecture, function, and dynamics of macromolecular complexes. Molecular simulation, X-ray crystallography, small-angle X-ray scattering, and traditional biochemistry form the core of our approach.
