Dr. Charles J Gillan

Dr. Charles J Gillan is a Principal Engineer at the Institute for Electronics Communication and Information Technology (ECIT). He obtained his PhD at the Queen’s University of Belfast in 1988 having carried out research in theoretical and computational physics in which He developed the R-matrix method to study resonant processes in the scattering of low energy electrons by small molecules. He continued this work until 1991 becoming an expert in the vector processing hardware commonly used in HPC at that time Cray X-MP, Y-MP, Cray 2 and IBM 3090. In 1992 and 1993 he worked on IBM Mulliken® package in the Theoretical Chemistry group at the IBM Research Division in San Jose, California.

Subsequently he moved to New York, working a project leader on a low latency subsystem for sovereign debt instrument trading within the Global Report product of ADP Inc.
