Associate Prof. Dr. Hijaz Ahmad completed his MS in computational mathematics from the Department of Mathematics, COMSATS University Islamabad, Wah Campus. In 2022, he completed his PhD in Computational and Applied Mathematics from the Department of Basic Sciences and Islamiat, University of Engineering and Technology Peshawar, Pakistan and then he started his Post-doc from Lebanese American University, Beirut, Lebanon. His research work is focused on the development and advancement of numerical techniques for finding the numerical solution of mathematical models in the form of partial differential equations and fractional partial differential equations arising in finance, computational biology, and different disciplines of engineering. He has introduced modified variational iteration algorithm-I and modified variational iteration algorithm-II for the numerical solution of nonlinear partial differential equations and fractional iteration algorithm-I for finding the numerical solution of nonlinear non-integer order partial differential equations. The scope of his research is quite broad, covering numerical analysis, fractional calculus, mathematical biology and mathematical physics. Dr Ahmad is included in the World's Top 2% Scientists 2022, 2023 and 2024 (by Stanford University and Elsevier).
