About CSS Founder Gary M. Johnson

Dr. Johnson’s career, of more than 40 years, includes expertise in: management of high performance computing, applied mathematics, and computational science research activities; advocacy, development, and management of high performance computing centers; development of national science and technology policy; creation of education and research programs in computational engineering and science; and formulation of novel algorithms for the numerical simulation of complex phenomena and the solution of computationally-intensive problems.

Dr. Johnson’s experience includes work in Academia, Industry and Government. He has held full professorships at Colorado State University and George Mason University, been a researcher at United Technologies Research Center, and worked for the Department of Defense, NASA, and the Department of Energy.

Within DOE’s Office of Science, Dr. Johnson was responsible for developing collaborative research activities based on high-performance computing and computational science. He was instrumental in structuring DOE’s global climate modeling and computational biology research partnerships. Dr. Johnson laid the ground work for the establishment of additional partnerships in advanced nuclear energy systems, subsurface sciences, cybersecurity for open science, and alternative & renewable energy. He further explored and advocated the creation of programs for the modeling and simulation of the electric grid and for using high performance computing more effectively in data-intensive applications. Dr. Johnson was also responsible for liaison activities related to high performance computing and its applications, between the Office of Advanced Scientific Computing Research and various international organizations, including the Japan’s Next-Generation Supercomputer Project, the European Union’s Partnership for Advanced Computing in Europe (PRACE), and other Asian and European organizations.

He is a graduate of the U.S. Air Force Academy; holds advanced degrees from Caltech and the von Karman Institute; and has a Ph.D. in applied sciences from the University of Brussels.
