Research Interests

My research examines the voluntary and respiratory-related neuromuscular control of upper airway muscles.


Under my current� (K-23) award I proposed a series of experiments to be conducted in human subjects that will examine the modulation of human hypoglossal motor unit activities as a function of sleep and wakefulness, in response to respiratory-related sensory stimuli and during volitional movement. These experiments will provide insights into the nervous system (efferent and afferent components) control of the tongue muscles in healthy human subjects that will have implications for the neural control of movement in the broadest sense.

This research will provide the foundation for future studies of lingual motor control in upper airway muscles during more complex oromotor functions such as swallowing. The research extends and develops upon� my previous research� that focused on� the respiratory-related control of tongue muscle activities in the spontaneously breathing anesthetized rat, and will� lay the foundation� for an independent research program that combines behavioral and neurophysiological approaches to study lingual neuromuscular control in human and lower mammalian model systems.
