Research Interests

Since the start of my research career in the early 90s my interest has been the role of the autonomic nervous system in maintaining homeostasis in response to physiologic perturbations and in diseases. Early on, I studied sympathetic modulation of cardiac and vascular function using sympathetic nerve activity recordings and electrical stimulation of peripheral sympathetic nerves or hypothalamic brain regions controlling autonomic function in conscious rats. More recently I also focused on the role of the parasympathetic nervous system and developed miniaturized nerve stimulators that can be chronically implanted in rats and mice. Using these stimulators we investigated the differential effects of afferent vs. efferent vagal nerve stimulation on glucose metabolism and in our most recent study we also used the implantable nerve stimulators in a chronic protocol to investigate the role of the parasympathetic nervous system in preventing cardiovascular end-organ damage in severely hypertensive rats.
