Research Abstract
Dr. Gee is a neuropharmacologist whose principal interests are mechanisms of regulation of signaling through ligand-gated ion channels and the identification of novel signal transduction-based therapeutic strategies for the treatment of disorders amenable to modulation of signal transduction pathways.

His laboratory is currently characterizing the pharmacology of several novel allosteric modulatory sites on the GABAA receptor complex and the alpha7 nicotinic receptor using tissue and recombinantly derived receptors as well as studying the behavioral consequences of modulatory site activation. These sites include for example one for certain neuroactive steroids and another for compounds related to the fluoroquinolone antibiotics.

The overall mission of the lab is to identify and characterize novel modulatory sites on ligand-gated ion channels, design and synthesize ligands for these sites and evaluate their potential as novel therapeutic agents useful in the treatment of human diseases.
