Biography

I am originally from Nigeria, the largest country in Africa. I love to teach and talk Mathematics. Besides Mathematics, I engage in many other activities such as traveling, writing, playing table tennis and football, and watching movies. Though I take my research very seriously, my passion is helping in the area of STEM Ed and reaching out to minority in STEM Ed.

Research Interests

My research is broad and of great importance in many applications. I work in the areas of numerical analysis (algorithms & analysis for partial differential equations, integer and non-integer order), computational mathematics (simulations in application, PDE models, optimization), nonlinear operator theory involving fixed point algorithms, variational inequality, optimization and variational analysis, equilibrium problems, and nonlinear integral equations. Many of the systems I work with involved non-smooth or mismatched initial/boundary conditions which have applications in biochemical and biological pattern formations. My recent work is also in modeling, analysis, and simulation of some infectious diseases such as the generalized Chagas vectors re-infestation model and the novel coronavirus (COVID-19). Data science and data analytics are integral part of my new research areas with applications in biology, medicine, and business
