Did research activities involving analysis of boundary and initial-value partial, ordinary differential and difference equations, and their applications to biological problems. Analysis includes existence of solutions, and their local and global asymptotic stabilities, bifurcation of solutions as model parameters change. Physical problems studied are epidemiology (effects of vertical transmission, insecticide resistance and temperature on vector-borne diseases), predation and competition for natural resources and the effects of variable environmental factors. Research results from individual, and collaborative works are published, presented at national and international conferences. Additional work involves mentoring undergraduate students who got awards at conference presentations.
Mathematical Biology: Dynamical Systems (Initial and Boundary Value Partial, Ordinary Differential, and Difference Equations) and applications to epidemiology such as vector-borne diseases, insecticide resistance, intra-specific predation and competition for natural resources.
Published research results done individually as well as collaborating with other researchers, mentored undergraduate students, served as a reviewer by invitation, invited to give a talk at conferences.
