In general, my research interest is control of the circulation as it relates to regulation of blood pressure and blood flow during exercise. One research focus I have concerns afferent aspects of cardiovascular reflexes from skeletal muscle. This involves determination of various metabolic stimuli that are capable of eliciting or modulating cardiovascular responses.
I am also interested in the contribution of specific hormones/neuropeptides e.g. vasopressin, oxytocin, angiotensin II, and endothelin to peripheral, spinal, and central modulation of the cardiovascular response to exercise in normal and pathophysiological conditions i.e., heart failure and hypertension.
A recent research focus is vascular biology as it relates to endothelial function during exercise. We are studying human vascular endothelial cells to determine if supplementation with omega-3 polyunsaturated fatty acids enhances activation and/or expression of important proteins associated with nitric oxide production.
Studies of healthy individuals and heart failure patients are also being conducted to determine if these omega-3 fatty acids are capable of enhancing skeletal muscle blood flow and lessening systemic vascular resistance during dynamic exercise.
