While at AIMS, Robert reviewed some previous mathematical models of Ebola Virus infection by different researchers and summarized their results. Further, he formulated a more realistic deterministic ordinary differential equation (ODE) model, performed the local stability analysis of the Disease Free Equilibrium (DFE), and computed the basic reproduction number.

After AIMS, Robert completed a Post graduate Diploma in Air Traffic Management and currently works as Air Traffic Controller at Kenya Civil Aviation Authority.
