In this talk we present a novel boundary integral equation method for the numerical solution of problems of scattering by obstacles and defects in the presence of layered media. This new approach, that we refer to as the windowed Green function method (WGFM), is based on use of smooth windowing functions and integral kernels that can be expressed...

Low Reynolds number swimming of microorganisms in Newtonian fluids is an extensively studied classical problem. However, many biological fluids such as mucus are mixtures of water and polymers and are more appropriately described as viscoelastic fluids. Recently, there have been many studies on locomotion in complex...

Adaptive mesh refinement (AMR) algorithms are one of two necessary tools for grand challenging problems in scientific computing. Reliability of computer simulations is responsible for accurate computer predictions/designs. Efficient and reliable a posteriori error estimation is the key for success of AMR algorithms and the reliability of computer...

This talk introduces a twogrid and a bootstrap multigrid
finite element approximations to the LaplaceBeltrami eigenvalue
problem on closed surfaces. The latter can be viewed as a special case
of the BAMG (Bootstrap Algebraic MultiGrid) framework applying on
surface finite element method. Several interesting phenomena for
approximating...

Abstract: The dynamics of complex biological systems is often driven by multiscale, rare but important events. In this talk, I will first introduce the numerical methods for computing transition states, in particular, the Optimizationbased Shrinking Dimer (OSD) method we recently proposed. Then I will give two applications of rare events and...

Directed cell movement, chemotaxis, is a part of normal physiological processes such as wound healing, immune response and embryogenesis. However, this pathway can also be hijacked during tumor development, allowing cancer cells to metastasize. In this talk, I will discuss an ongoing collaboration in modeling the regulation of actin cytoskeleton...

The enteric nervous system (ENS) in our gastrointestinal tract, nicknamed the ``second brain'', is responsible for normal gut function and peristaltic contraction. Embryonic development of the ENS involves the colonization of the gut wall from one end to the other by a population of proliferating neural crest cells. Failure of these cells...
