Richard W. Riley College of Education and Leadership
I am a professor of mathematics. I taught mathematics courses at all levels and worked in many places. I joined Walden University in 2009. In my research, I work on functional and difference equations. In addition, I am interested in dynamical systems, numerical analysis and symbolic computations, and mathematics education. Furthermore, I am a referee for a dozen of highly renowned journals of mathematics; and a reviewer for the Mathematical Reviews of the American Mathematical Society, and the Zentralblatt Math.
