Johnson, Unyime Victor is an Assistant Lecturer in the Department of Mathematics and Statistics at Redeemer’s University and a PhD researcher in Applied Mathematics. Her research focuses on mathematical modelling, computational fluid dynamics, and contaminant transport in environmental and wastewater systems. She specialises in spectral numerical methods for solving nonlinear differential equations arising in porous media and reactive transport phenomena. She obtained her M.Sc. in Mathematics with distinction from Redeemer’s University, where she was recognised as the best graduating student, likewise making a first-class during her B.Sc. in Mathematics and Statistics from Ignatius Ajuru University of Education. Her current research interests include environmental modelling, water quality management, machine learning for environmental systems, and sustainable wastewater treatment technologies.
