Note: Professor Benjamin is on sabbatical for the Spring Semester of the 2023-2024 academic year.
Alfonso Castro, PhD, McAlister Professor of Mathematics, specializes in applied mathematics, differential equations and nonlinear functional analysis. Castro’s research areas include partial differential equations (including semilinear equations with discrete spectrum), variational methods, inverse-function theorems and water waves (solitons).
Castro was awarded a 2012 Simons Foundation Collaboration Grant for Mathematicians to support his research project, “Solvability of semilinear equations with discrete spectrum,” which involves equations fundamental to every area of science.
Castro is the co-founder and managing editor of the Electronic Journal of Differential Equations, a pioneering journal in paperless publication that publishes in excess of 150 research papers per year, accessible free of charge via the Internet.
Castro has served in several positions for the American Mathematical Association, including chair of the Human Rights Committee of the AMA.
