He is a professor in the Applied Mathematics and Statistics department [1] and founding Director of the Institute for Advanced Computational Science at Stony Brook University[2] with a $20M endowment.
Dr. Harrison comes to Stony Brook from the University of Tennessee and Oak Ridge National Laboratory, where he was Director of the Joint Institute of Computational Science,[6] Professor of Chemistry and Corporate Fellow.
He has a prolific career in high-performance computing with over one hundred publications on the subject, as well as extensive service on national advisory committees.
In 1992, he moved to the Environmental Molecular Sciences Laboratory of Pacific Northwest National Laboratory, conducting research in theoretical chemistry and leading the development of NWChem, a computational chemistry code for massively parallel computers.
In addition to his DOE Scientific Discovery through Advanced Computing (SciDAC) research into efficient and accurate calculations on large systems, he has been pursuing applications in molecular electronics and chemistry at the nanoscale.
