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...

Hydrodynamical evolution in a gravitational field arises in many astrophysical and atmospheric problems. Improper treatment of the gravitational force can lead to a solution which oscillates around the equilibrium. In this presentation, we propose a recently developed wellbalanced discontinuous Galerkin method for the Euler equations under...

In the numerical simulation for fluidstructure problems, many different possible combinations of coordinate systems can be used for fluid and structure problems. While Eulerian coordinate is almost always used for fluid problems, either Eulerian or Lagrangian coordinate can be used for structure problems. In this talk, I will...
