My area of interest is numerical methods in Engineering. Especially I do write code (Matlab, C, Jupiter Notebook, COMSOL-JAVA application building, and Fortran) to solve various deferential equations (IVP and BVP) using the finite element method, finite difference method, and others for my research work. I am interested to work on developing new code in my field.
