2014 research

Currently, the direction of my lab is to examine peripheral autonomic and microvascular function in humans.  This area of research utilizes an in vivo approach to investigate the mechanisms of how cutaneous vessels respond to local or whole-body thermal stimuli.  The utility of measuring vascular reactivity in the skin extends to 1) understanding thermoregulatory mechanisms, 2) an accessible means of studying general microvascular function, and 3) a prognostic indicator of cardiovascular disease since alterations in microvasculature function often precedes more systemic impairment with cardiovascular disease states.
