Charles Eaker, Ph.D.

Professor Eaker obtained a B.S. in chemistry from Michigan State University in 1971 and a Ph.D. in physical chemistry from the University of Chicago in 1974. His Ph.D. thesis was titled "A Semi-empirical Multiconfigurational Self-Consistent Field Theory." He was a R.A. Welch Postdoctoral Fellow at the University of Texas at Dallas in 1974-76. He joined the faculty at University of Dallas in 1976.

Dr. Eaker retired from UD in May of 2017 and we wish him well in his future ventures.

Research Interests

Dr. Eaker's research involves the use of computers to study the dynamical aspects of chemical reactions. This work requires the calculations of forces of interaction between atoms and molecules, the solution of differential equations governing the motion of the reacting atoms and molecules in a reaction, and the analysis of the product molecules. Two particular interests are nonadiabatic reactions and fast Fourier transform techniques for the quantization of reactants and the analysis of products.
