Ehigie Julius Osato

Associate Professor Julius Osato Ehigie is a faculty member in the Department of Mathematics, Faculty of Science, University of Lagos, Nigeria. He specializes in computational and applied mathematics, with core expertise in developing high-order numerical methods for oscillatory and fractional differential equations.

Education:

• B.Sc. Mathematics, Lagos State University, 2006
• M.Sc. Applied Mathematics, University of Lagos, 2009
• Ph.D. Mathematics, University of Lagos, 2014

Research Interests:

Ehigie’s research revolves around computational mathematics and scientific computing, focusing on fast, high-order accurate schemes such as Runge-Kutta and exponentially fitted integrators for periodic and oscillatory initial value problems. He applies these techniques to diverse areas including genetic regulatory systems, celestial mechanics, nonlinear atomic vibrations, air-pollution tracking models, and biological wave dynamics.

His recent publications exhibit a clear trend toward exponential integrators and structure-preserving methods for highly oscillatory systems, with practical applications in engineering (pipe vibrations), biology (genetic circuits), and nanotechnology (nanolattice oscillations), underscoring an interdisciplinary blend of rigorous numerical analysis and real-world modelling.
