Welcome

Assistant IIHR Research Engineer Sarah Vigmostad.

Assistant Professor Sarah Vigmostad

Sarah Vigmostad is an Assistant Professor in Biomedical Engineering at the University of Iowa. Her research area is computational biomechanics, with a focus on developing and applying computational methodologies for the study of disease formation and progression, improving disease treatment options and prosthetic device designs, and identifying biomechanics-related risk factors for diseases. Vigmostad and her research group’s efforts focus on developing a user-friendly multi-scale, fluid-structure interaction computer modeling package that can be applied to a multitude of biomedical problems.

I believe there are many applications for computational work in biomechanics, including the understanding of disease progression, the development of improved treatment modalities, and as a tool for physicians to use in determining therapeutic options.”

She and her group have employed their computational models developed  in the study of bioprosthetic and bicuspid aortic valve dynamics, aortic arch hemodynamics, mitral valve mechanics, micro-scale modeling of RBCs (using NURBS isogeometric modeling to enable multi-scale coupling), and the acoustics and fluid dynamics of voice production. More recently, in an effort to create more user-friendly and widely applicable modeling tools, the group has developed imaging-to-modeling and movie-to-modeling capabilities using a level-set based segmentation algorithm and optical flow techniques. This has enabled more straight-forward implementation of patient-specific 3D & 4D data, the first step in developing virtual surgical tools for better treatment planning.
