Col. Gregory H. Johnson
Gregory H. Johnson is the President and Executive Director of the Center for the Advancement of Science in Space (CASIS).
As Executive Director of CASIS, Johnson is responsible for leading the organization in the identification of novel applications and the development of new partnership opportunities that will advance utilization of our nation's orbiting laboratory and will accelerate development of the emerging commercial market in low earth orbit.
Prior to CASIS, Johnson was a decorated officer and fighter test pilot with the United States Air Force. Among his assignments, he flew over 60 F-15 combat missions in support of the Persian Gulf in the early 1990’s. Retiring as a full Colonel after nearly 25 years, Johnson logged over 5,000 flight hours in more than 50 different aircraft.
In 1998, Johnson was selected as a NASA Astronaut and ultimately piloted two Space Shuttle missions (STS-123 and STS-134, both aboard Space Shuttle Endeavour) where he spent nearly 32 days in orbit contributing to the assembly of the ISS. In October 2011, Johnson served as the Associate Director for external programs at NASA Glenn Research Center in Cleveland, OH. In that role, Johnson managed all public affairs, outreach and educational programs at the Center.
Johnson received his B.S. in aeronautical engineering from the U.S. Air Force Academy, his M.S. in flight structures engineering from Columbia University and his M.B.A. from the University of Texas at Austin.
