Dr. daCosta examines structure-function relationships in a class of proteins called ligand-gated ion channels, which are ion-conducting pores embedded in cell membranes.  Evolved to convert chemical signals into electrical impulses, ligand-gated ion channels mediate fundamental physiological processes, are implicated in numerous human diseases, and are the targets of a wide variety of drugs.  Dr. daCosta seeks to both control ligand-gated ion channel function with chemistry, and to engineer ligand-gated ion channels with unique and useful properties.
