Thermal and Vascular Physiology Laboratory

The Thermal and Vascular Physiology Laboratory focuses on neural control of the cardiovascular system, with emphasis on the skin. Ongoing lab projects include: identifying the consequences of skin grafting on the ability of burn survivors to regulate internal temperature; understanding how heat stress compromises the control of blood pressure during hemorrhage; and identifying mechanisms responsible for increases in sweating and skin blood flow during post-menopausal hot flashes.

Interests

Dr. Crandall’s research interests revolve around neural control of the cardiovascular system, with emphasis on how thermal stress modifies this control. Research areas range from integrative thermoregulatory studies in healthy and unique populations (e.g., skin graft patients) to mechanistic studies on the skin microcirculation. Clinical applications of this work include improved blood pressure control during hemorrhage (particularly in heat stressed individuals such as soldiers, construction workers, etc), improved temperature regulatory capacity injured/diseased individuals (e.g., skin graft patients, congestive heart failure, etc), and a better understanding of the mechanisms responsible for cutaneous responses during the post-menopausal hot flash.​


Current Projects

  • Effects of burn injuries on thermoregulatory and cardiovascular responses in soldiers.
  • Effects of exercise in burn survivors.
  • Mechanisms by which heat stress compromises blood pressure control during hemorrhage.
  • Effects of aging and cardiac function with Dobutamine and heat stress.
  • Hemodynamics during Leg Heating in Peripheral Artery Disease (PAD).
