Computational models are essential for assessing quantities that are otherwise immeasurable.  In general, my work focuses on the design of large-scale parallel applications targeting problems in physics. I design large-scale parallel applications that enable the study of research problems in areas ranging from cardiovascular disease to wireless networks to drug development.

The recognition of the role hemodynamic forces have in the localization and development of disease has motivated large-scale efforts to enable patient-specific simulations. When combined with computational approaches that can extend the models to include physiologically accurate hematocrit levels in large regions of the circulatory system, these image-based models yield insight into the underlying mechanisms driving disease progression and inform surgical planning or the design of next generation drug delivery systems. The scale of these simulations requires the use of massively parallel supercomputers, so much of my work involves the development of methods to maximize parallel efficiency.  Through funding provided by my recent NIH Early Independence Award, I am expanding the scope of projects to address not only vascular diseases, but also treatment planning and the movement of circulating tumor cells in the bloodstream.

October 6, 2014.  Amanda receives the NIH Early Independence Award. Given through the NIH Common Fund as part of its "High-Risk, High-Reward Program", this award provides a mechanism for exceptional early career scientists to move rapidly into independent research positions by essentially omitting the traditional post-doctoral training period.
