Professor Richard Neidinger received his B.A. degree at Trinity University and his M.A. and Ph.D. degrees from the University of Texas at Austin, joining the Department in 1984. His research and upper-level teaching has focused on analysis and computer applications in mathematics, including fractals, chaos and topics in numerical analysis, especially the theory and implementation of automatic differentiation. His interests also include using technology to illuminate mathematical understanding. In 1990, the Mathematical Association of America honored Professor Neidinger with the George Pólya Award for expository excellence in The College Mathematics Journal. He originally designed Davidson's MAT 118 course, Exploring Mathematical Ideas, and MAT 437, Dynamical Systems, and has collaborated in developing these and many courses including calculus.
