Mohamed Amine Khamsi (born 1959 in Morocco) is an American/Moroccan mathematician known for his work in nonlinear functional analysis, the fixed point theory, and metric spaces.
Since 1989, Khamsi has been a faculty member at the University of Texas at El Paso (UTEP), where he became a full professor of mathematics in 1999.
Currently, Khamsi is a professor of mathematics at Khalifa University in Abu Dhabi, where his research continues to impact fields such as nonlinear analysis, fixed point theory, and their applications in optimization and data science.
His research collaborations with mathematicians like W. M. Kozlowski have led to new developments in Modular Function Spaces and their applications to nonlinear problems.
He is the co-author, with W. A. Kirk, of the widely cited book An Introduction to Metric Spaces and Fixed Point Theory, published by Wiley in 2001.
