 current student opportunities
Available: 10/10/11, Expires: 10/10/16

Students would participate in projects aimed at evaluation of atherosclerotic plaque structure and inflammation in specific patient populations. A searchable database of thousands of previously imaged and categorized patients is available, allowing the student to identify a specific patient sub-group and its control group. Thereafter, by evaluating the images of those patients, a comparison of the atherosclerotic plaque phenotypes is feasible.
