Vascular Model Repository

...

What is it

The vascular model repository, a sister project of SimVascular, is a library of computational models of normal and diseased human cardiovascular and pulmonary anatomy and input and output boundary conditions for various physiologic states. These models can be used to simulate cardiovascular and pulmonary solid and fluid mechanics and will provide spatially and temporally-resolved benchmark solutions that can be used by academic, government and industry researchers to verify their computational methods. Most models in the repository were created with SimVascular. The SimVascular project provides an open source package for simulation to accompany the data provided in the model repository.

Alison Marsden

Bio notes

Alison Marsden is an associate professor of Pediatrics (Cardiology) and of Bioengineering, by courtesy, of Mechanical Engineering at at Stanford University. She graduated with a bachelor’s degree in Mechanical Engineering from Princeton University in 1998, and a PhD in Mechanical Engineering from Stanford in 2005 working with Prof. Parviz Moin. She was a postdoctoral fellow at Stanford University in Bioengineering and Pediatric Cardiology from 2005-07 working with Charles Taylor and Jeffrey Feinstein. She was the recipient of an American Heart Association postdoctoral fellowship, an AHA beginning grant in aid award, a Burroughs Wellcome Fund Career Award at the Scientific Interface, an NSF CAREER award, and is a member of an international Leducq Foundation Network of Excellence. She has published over 60 peer reviewed journal papers, and her lab has received funding from the NSF, NIH, and several private foundations. Her work focuses on the development of numerical methods for simulation of cardiovascular blood flow problems, medical device design, application of optimization to large-scale fluid mechanics simulations, and use of engineering tools to impact patient care in cardiovascular surgery and congenital heart disease.
