My research involves modeling oxygen transport and blood flow regulation in the microcirculation, which is the part of the circulation consisting of the smaller blood vessels that supply oxygen to the majority of surrounding tissue. I use mathematical and computational models to try to answer questions about how blood flow and blood flow regulation affect tissue oxygenation, in particular in networks of microvessels with heterogeneous structure.
