Computational models are essential for assessing quantities that are otherwise immeasurable.  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.

A main focus of my research is a multiscale model coupling the fluid dynamics of blood plasma with the movement of red blood cells from which we can start to elucidate trends and aid prognosis of cardiovascular disease based on high-resolution patient-specific data. 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.

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. LLNL Press Release.

October 3, 2014. Amanda is awarded a Tier Two allocation in the 9th Institutional Unclassified Computing Grand Challenge at Livermore National Laboratory for the proposal titled "Studying the Impact of Physiological Conditions on Cardiac Risk Factors". This will provide substantial compute time on the Vulcan and Sierra supercomputers.
