ORISE Post Doctoral Fellow
June 2001 -November 2002
Hydrodynamics and Acoustics Branch, Division of Physical Sciences
Performed basic research to objectively study the amount of red blood cell damage (hemolysis) caused by medical devices in order to better predict hemolysis. One type of device studied was the class of roller pumps used in cardiopulmonary bypass surgery. Other studies involved determination of a reliable bench-top blood fragility tester. Laboratory studies will be continued into the future and be complemented with PIV flow visualization and Fluent FEM of several blood damage models.
