As both a practicing neuroanesthesiologist and a scientist, I became interested in the pharmacology involved with sedation, sleep, coma, and anesthesia.  For several years, I have been successfully collaborating with Drs. Rye and Jenkins on projects related to idiopathic hypersomnia and its potential mitigation with allosteric modulators of the GABA(A) receptor (e.g., drugs such as flumazenil).  We have also successfully determined the baseline concentration of GABA in human CSF.  My primary clinical interests are in neuroanesthesia and geriatric anesthesia, in particular aneurysm surgery, spine surgery, EEG and recovery from general anesthesia.  I am confident that through our endeavors we will enhance what we know about the role of neuronal circuits in arousal from sleep and anesthesia.
