I am a Lecturer in the Department of Mathematical Sciences at Auckland University of Technology, New Zealand. My research interests lie in the application of dynamical systems theory to practical problems, including neuroscience, cardiovascular systems, and epidemiology.

Before joining AUT, I served as a postdoctoral fellow at the EpiCentre, within the School of Veterinary Science at Massey University in Palmerston North, New Zealand. At the EpiCentre, I worked on various research projects including risk factor analysis of avian influenza and modelling of infectious bursal disease in commercial flock.

After my PhD, I worked as a postdoc with Associate Professor David J. W. Simpson on robust chaos in switched dynamical systems in relation to the project titled “Organised chaos: Using geometry to explain robust chaotic dynamics in switched dynamical systems.”. The project was funded through the Royal Society of NZ Marsden Fund. Click here for research output .

My PhD research was on mathematical analysis of the physiology of excitable cells, in particular smooth muscle cells. I used bifurcation theory to study electrophysiological activities in a single cell and analysed the collective behaviour of the smooth muscle cells through gap junction coupling between adjacent cells. The results showed that coupled cells can exhibit irregular spiking of action potentials. My supervisors are Dr Richard G. Brown, Assoc. Prof Bruce van Brunt, and Dr David J. W. Simpson. Research publications: I, II.

Before joining Massey, I received an MSc in Mathematical Sciences from African Institute for Mathematical Sciences in Ghana and a B.Tech in Industrial Mathematics from the Federal University of Technology, Akure in Nigeria. I also had a diploma in Statistics from the Federal Polytechnic Ede in Osun State, Nigeria.
