Bio

The goal of my research career is to investigate pharmacological treatments of sleep-related breathing disorders (e.g. obstructive sleep apnea [OSA]). I am a neuroscientist studying respiratory modulation during sleep.

My published and preliminary results show that dronabinol, a cannabinoid, injected locally into the nodose ganglia (cell bodies of the vagus nerves containing cannabinoid receptors) attenuates reflex apnea and increases upper airway activity in rats; apnea attenuation, but not increases in upper airway activity, is blocked by systemic cannabinoid antagonism. Moreover, systemic administration of dronabinol in chronically instrumented conscious rats decreases apnea index, but also decreases time spent in REM sleep.

Combined with the proof-of-concept human trials showing a decrease in OSA severity with dronabinol administration, and a rat model of apnea basic science investigations I have conducted, dronabinol has the potential of being the first drug approved for OSA treatment. However, cannabimimetic modulation of respiration needs clarification. It is my goal to investigate the cannabinoid dependent and independent receptor-mediated mechanisms of the peripheral and central nervous systems that augment state-dependent respiratory control.

I will study the neurophysiological, neurobiological, and neuropharmacological mechanisms of cannabinoid modulation of the respiratory circuitries (both peripherally and centrally) implicated in sleep-related breathing disorders.

Co-localization of 5-HT3 and Cannabinoid Receptors on Rat Nodose Ganglion Cells (6 month project)
The goal of this study is to: a) elucidate the expression of serotonin and cannabinoid receptors within nodose ganglia; b) identify any co-localization of 5-HT and cannabinoid receptors; and c) determine the functional impact of receptor activation using real-time calcium (Ca2+) imaging.
