My research involves applying physics to problems inspired by health and related medical technology. In particular, my group focuses on blood flow at both the macroscopic and microscopic levels. We develop models and techniques to study variables that affect flow parameters in blood vessels, such as in arteries, aneurysms, or the developing fetus.  

Primarily this work focuses on the development of methods using ultrasound imaging and particle imaging velocimetry (PIV) to map out of macro- and micro-scale flow, as well as the application of lumped-parameter models using pressure and flow data to derive vascular impedance parameters.

We also develop and use microfluidic devices, which are microscopic flow channels (50-500 um) where we can grow live cells and then study the real-time response of the cells to different types of flow stimulus. For these devices, we can use micro-PIV to accurately map out the flow in these miniature ‘lab-on-chip’.
