Rodrigo Villar, PhD

Biography

Dr. Rodrigo Villar's research uses postural changes and exercise as a framework to elucidate the role of perfusion pressure, O2 availability, and vascular conductance and resistance in the regulation of blood flow and O2 uptake and the implications for the muscular system especially the muscle pump.
