Research Interests

My earlier research focused on the neural control of breathing in human and nonhuman mammals with particular emphasis and interests in nervous system control of upper airway muscle activities in obstructive sleep apnea (OSA). Beginning in 2015, my interests have shifted toward sleep and sleep disordered breathing, especially those with mild, moderate or severe OSA. In this more recent phase, my laboratory is focused on assessing the potential benefits of a novel form of respiratory muscle strength training and its potential to offer a safe and effective means of lowering blood pressure, improving vascular health and sleep in older adults.
