  • Area of Specialization: Mathematical Modelling
  • Department of Mathematics

  • I am Mr. Marcus Ifeanyi Ossaiugbo, a Mathematician. I hail from Ukwuani Local Government Area of Delta State, and I am a Baptist by faith. My area of specialization is Mathematical Modelling. I obtained my Bachelor of Science Degree from the Delta State University, Abraka with a First Class (Honours) in Mathematics, which made me outstanding, as I also emerged as the Best Graduating Student of the prestigious University, 2014/2015 academic session. I also obtained my Master of Science Degree from the Department of Mathematics, Delta State University, Abraka. I am proud of my research ON OPTIMAL CONTROL OF THE PNEUMONIA DISEASE, which formed my Dissertation for the M.Sc. Degree Program. By the grace of God I have some publications on Mathematical Modelling of infectious diseases, ranging from "Mathematical Modeling and Analysis ofPneumonia Infection Dynamics" to "Bifurcation Analysis of a Mathematical Model for the Covid-19 Infection among Pregnant and Non-Pregnant Women". I am a proud member of Delta State University Covid-19 Research Team. Above all, see Rev. 1:8. Our God Almighty be praised forever more. Amen.
