Sleep apnea • upper airway • neuromuscular • clinical outcomes • cardiometabolic • congestive heart failure • pregnancy
My research focuses on obstructive sleep apnea, a condition characterized by repeated episodes of interrupted breathing during sleep due to blockage of the airway and understanding why the airway closes during sleep, and how the episodes of breathing interruption affect daytime alertness, thinking and energy levels, as well as the functioning of the heart and blood vessel system and some hormones. I am studying this in several different patient groups including patients with neurologic disease (multiple sclerosis and Parkinson's disease), patients with chronic heart failure, and in pregnant women who may also develop sleep apnea during pregnancy. I am also working to understand how best to treat sleep apnea when it occurs and minimize the complications that apnea can cause.
