Arden Ruttan

Associate Professor

Arden Ruttan received his Ph. D. in numerical analysis from Kent State University in August 1977. He was a postdoctoral fellow at California Institute of technology from 1977-1978 and an assistant professor at Texas Tech University from 1978-1983 before joining Kent State University in 1983. Currently, he is an associate professor of computer science. He is an associate member of the Institute for Computational Mathematics and a faculty associate of the NSF Center for Advanced Liquid Crystalline Optical Materials (ALCOM). His funding includes grants from Cray Research and Deutsche Forschungsgemeinschaft. His research interests are scientific computing, highly ill-conditioned mathematical computations, problem of apriori algorithm selection, apostiori error analysis for numerical routines, parallel implementations of above problems.
