The **Cardiovascular Modeling and Simulation Laboratory** (Boyce Griffith, PI) is a computational science research group at the University of North Carolina at Chapel Hill affiliated with the Departments of Mathematics and Biomedical Engineering, the Carolina Center for Interdisciplinary Applied Mathematics in the Department of Mathematics, and the McAllister Heart Institute at UNC School of Medicine.

We use methods of computational and applied mathematics, computer science, and bioengineering to develop physiological models of cardiac and cardiovascular function in health and disease. We participate in interdisciplinary collaborations encompassing clinical, experimental, and theoretical research, and involving applied mathematicians, computational scientists, engineers, biologists, and clinicians. *Broad goals of the group are to develop leading methods for biomedical simulation, and to apply these methods to important problems in medicine and biology, with the aim of advancing predictive simulation-based approaches to designing and optimizing cardiac and cardiovascular therapies and medical devices.*

We also work to develop, to maintain, and to distribute general-purpose software tools for computer modeling and simulation that serve as key research infrastructure for a growing number of independent research projects, not limited to cardiovascular applications. The primary software product of the group is *IBAMR*, which is a distributed-memory parallel implementation of the immersed boundary (IB) method with support for Cartesian grid adaptive mesh refinement (AMR). Although IBAMR was initially developed to enable large-scale simulations of cardiac fluid-structure interaction (FSI), this software is now used to simulate diverse systems in fluid dynamics and FSI in various fields of science and engineering. IBAMR has also been used to develop infrastructure for modeling electrophysiological systems, and for simulating electro-mechanical interaction in cardiac and neuro-muscular systems.
