Research

Juan M. Jiménez, a Research Associate faculty member in the Department of Pathology and Laboratory Medicine at the Perelman School of Medicine, is a trained fluid dynamics engineer. His research interests are in the area of biofluids, combining fluid dynamics and vascular biology concepts to study the development and progression of atherosclerosis in the cardiovascular system. Interestingly, at a site where a stent is deployed to treat atherosclerotic lesions, the stent design can play a major role in the newly modified flow field and can affect the development of neoatherosclerosis and thrombosis. My current research focuses on optimizing stent strut design for favorable vessel healing, improving endothelialization and decreasing in-stent thrombosis in order to decrease morbidity and mortality associated with stents. Another area of research interest involves studying how different blood flow fields can affect vascular wound healing post-injury. In addition, I am interested in understanding the effect of local fluid transport in the development of atherosclerotic lesions. In general, the distribution of cholesterol in the blood is homogeneous while atherosclerotic lesions develop heterogeneously within the cardiovascular system. My hypothesis is that the development of atherosclerotic lesions is affected by the local blood flow and ensuing fluid transport effects of this flow field.
