Dr. Johnson received his B.S. in Aeronautical Engineering from Purdue University. He worked for the Aerospace Division of the Boeing Company in Seattle, Washington for four years. He returned to Purdue University and earned an M.S. in Engineering and a Ph.D. in Mechanical Engineering at the Zucrow Laboratory. Dr. Johnson was a NATO Post-doctoral Fellow at the von Karman Institute for Fluid Dynamics in Brussels, Belgium. He joined Colorado State University in 1971 and taught in the Mechanical Engineering Department and the Computer Science Department. Prof. Johnson created the Center for Computer Assisted Engineering and the College’s Engineering Network Services (now Engineering Technology Services). He was chair of the Engineering Science major and in 1984 was named the George T Abell Endowed Chair in Engineering. On leaves from CSU, he was a Visiting Professor at the University of Kent in Canterbury, England, and at the California Institute of Technology in Pasadena, California. Dr. Johnson spent a sabbatical year as a researcher at Shape Data, Ltd. in Cambridge, England working on geometric modeling software. Dr. Johnson retired from Colorado State University in 1995. For eight years he served as Academic Vice-President of the National Technological University. In 2010 he rejoined the Mechanical Engineering Department at Colorado State University as a Senior Research Scholar/Scientist. He also taught on four Semester at Sea voyages. Dr. Johnson has published in computational fluid mechanics; solar energy; atmospheric science; rocket propulsion; optimal control theory; embedded control systems; modeling, simulation and computer assisted engineering; design of programming languages and computer graphics languages; and curriculum development in engineering education.
