  • Outstanding Research Award (junior level), Math Dept., Michigan Tech, 2008-2009.

RESEARCH INTERESTS:

  • The general areas of my interests include scientific computing, modeling/simulation and numerical methods for mathematical problems arising from science and engineering applications, such as mathematical biology, computational electro-physiology and computational fluid dynamics. My current specific research interests are focused on adaptive and multiscale algorithms for modeling cardiac dynamics. A few other numerical methods (other than those covered by my thesis work) that I have made intensive studies are Cartesian grid methods for elliptic boundary/interface problems, boundary integral methods accelerated by fast multipole algorithms, and composite backward differentiation formulas (CBDFs) for initial value problems.

NUMERICAL SIMULATIONS:

    To view the following animations, it is better to download them first and then open
    with a media player such as "QuickTime Player" due to the large size of the files.
