Rafael Luís is a professor of mathematics at the University of Madeira, Portugal, and a researcher at the Center for Mathematical Analysis, Geometry and Dynamical Systems, University of Lisbon, Portugal. He received his Ph.D. in mathematical analysis from the University of Madeira and has extensive expertise in discrete dynamical systems. His research primarily focuses on stability and bifurcation phenomena in discrete-time models arising in biology, population dynamics, and economics. Over the years, he has also contributed to the theory of periodic nonautonomous discrete dynamical systems. He has authored numerous articles in international peer-reviewed journals and regularly serves as a reviewer for leading journals in the field. He has also actively organized and participated in international scientific conferences. He is a member of the International Society of Difference Equations (ISDE). His current research focuses on stability theory, bifurcation analysis, and the qualitative behavior of nonlinear discrete dynamical systems, with applications to ecology and economics.
