Area of my interest or research is developing schemes for computational wave propagation which are less dispersive and dissipative. Primarily, I study dispersive and dissipative properties of low and high order schemes in detail for acoustics and electromagnetic wave propagations. My interests are two fold providing qualitative description of the nature of the dispersive and dissipative behavior of the schemes along with precise quantitative statements of the accuracy in terms of the mesh size, the order of the scheme and the wave number which serves as an a priori for practical problems. I also work in the development of novel non-standard quadrature rules for the practical implementation numerical schemes for wave propagation problems.

 

Following are few achievemetns I have earned so far:
