Research
Many real life problems are modeled by nonlinear differential equations. However, several methods in literature require linearization of the governing equations in order to have closed form solutions to the problems or sometimes to be able to apply the methods. In an attempt to linearize the original governing equations, many vital information are lost and the accuracy of the solution might as well be compromised. To overcome this challenge, my current research is directed towards derivation and applications of efficient block linear multi-step methods for certain classes of non-linear initial value problems including stiff and singular problems. In addition, formulation and applications of accurate hybrid implicit block methods using certain basis functions for the numerical solution of non-linear boundary value problems. I have worked extensively on the development of various methods based on spline functions, Chebyshev polynomials, etc for solving boundary value problems, integral equations, integro-differential equations and partial differential equations. I have equally worked on modelling, epidemiology and semi- analytical methods of solution for differential equations.
