Bio

Dr. James Greer is the Technical Director of the U.S. Air Force Academy’s Center for Aircraft Structural Life Extension (CAStLE). He is also on the faculty as an Associate Professor of Engineering Mechanics in the Department of Engineering Mechanics. Dr. Greer earned his PhD in Aeronautical Engineering from the Air Force Institute of Technology in 1996 where he advanced the theory for, and developed a finite element analysis tool for, the analysis of thick composite shells having complex curvature and significant through-thickness stresses. He then worked as Deputy Division Chief in what is now the Aerospace Systems Directorate of the U.S. Air Force Research Laboratory (AFRL/RQ) before coming to the Air Force Academy in 1997.

As Technical Director of CAStLE, Dr. Greer oversees the technical activities of a $30M (annual) portfolio of research with Air Force, Navy, Department of Defense (DoD) and NASA. Active research areas include fatigue, fracture mechanics, failure analysis, corrosion mitigation, flight data collection and analysis, forensic teardown analysis, and education and training.

Dr. Greer was a member of the USAFA faculty from 1997 through 2004, and retired from active duty service as a Full Professor. He then served CAStLE as a contract Principal Engineer for six years before returning to government service in 2010 in his current position.

During his active duty USAF career, Dr. Greer worked as a research and development engineer in various project areas including ramjet propulsion, strategic communications, flight testing, precision airdrop systems, and landing gear testing.

Dr. Greer is a registered Professional Engineer in the State of Colorado, and has taught the following courses:

Engr 100 – Introduction to Engineering Systems
Engr Mech 220 – Fundamentals of Mechanics
Engr Mech 320 – Dynamics
Engr Mech 330 – Mechanics of Deformable Bodies (Course Director)
