My research program is in the area of applied computational mathematics with biological applications. I am interested in numerical methods for and computer simulations of fundamental mechanical and/or biological processes which involve incompressible viscous fluids and elastic deformable boundaries. There are two major components of my research program: development of numerical methods for fluid-flexible-structure-interaction problems including extension/improvement of the immersed boundary (IB) method, and applications of these methods to problems in life science/ biomedical engineering.
Currently I am working on 1)A new 3D parallel IB method with application to hemodialysis; 2)Multiscale modeling and simulation of interstitial fluid flow over an osteocyte in bone matrix; 3)An extreme scale IB method with applications; 4)Modeling and simulation of cancer cell metastasis.
