I am an Assistant Professor of Radiology and Bioengineering with interest in developing methods for computational image analysis, anatomical shape modeling, and interactive visualization to guide surgical interventions. Specifically, my work has focused on modeling heart valve morphology and dynamics in 3D echocardiography for risk stratification and planning of heart valve repair surgery. The goal is to use automated image analytics to predict surgical outcomes, to inform development of surgical guidelines, and to advance minimally invasive therapies for the treatment of cardiovascular disease.
Research Areas
3D/4D segmentation and modeling of heart valves in echocardiographic images with applications to surgical treatment of valvular regurgitation
