Vascular Physiology Laboratory

Vascular Physiology Lab Group

Researchers in the Vascular Physiology Lab study vascular function in healthy and diseased states and in response to exercise and diet, using a variety of techniques to examine macro- and microvascular function as well as arterial stiffness.

Research Focus

The focus of the Vascular Physiology Lab is studying vascular function/dysfunction in healthy and diseased states, with particular emphasis on chronic kidney disease. Additionally, vascular responses to exercise and diet are studied. A variety of techniques are utilized to examine macro- and microvascular function as well as arterial stiffness in humans and animal models.

Current Projects

Studies in Chronic Kidney Disease (CKD)
Exercise Training in CKD
The lab is currently investigating the effect of exercise training on vascular function in patients with CKD. We are also interested in understanding the mechanisms of exercise intolerance in CKD.

Mechanisms of impaired vascular function in CKD
The lab continues to study the mechanisms of impaired vascular function in CKD. We are also currently performing intervention studies to determine the effect of several with nutraceuticals on vascular function and exercise/physical performance in CKD.

Vascular Effects of Dietary Salt in Humans with Salt-Resistant BP
In collaboration with Dr. Bill Farquhar and his Cardiovascular Research Lab, we are exploring the effects of dietary salt on vascular function. Our hypothesis is that excess dietary salt adversely affects vascular function, independent of blood pressure.
