    Collapse overview

    My research is devoted to understanding the neural control of autonomic functions. Specific areas of interest are the genesis of respiratory rhythm, the coordination of breathing and swallowing, and the maintenance of circulation during upright posture. The major goal is to understand how normal control mechanisms break down and lead to certain common disease states: central apnea, neurogenic aspiration, and neurally mediated syncope.
