I am interested in the modeling and biomolecular simulation of integral membrane proteins. Recently I have been focusing on critical neuroreceptors, such as the GABAA receptor and the NMDA and AMPA glutamate receptors.  More info.  Additionally, I have been working on small molecule permeability studies, to investigate the energetic barriers associated with crossing a lipid bilayer.
