INSTRUCTOR

Michael Mohaghegh has worked for The Boeing Company for 50+ years on programs, core groups, product development, commercial and military aircrafts, and aircraft support groups. He is a Boeing Technical Fellow in aircraft structures and materials and presently the Chief Editor of The Boeing Company Design Principles Manuals. Mike is an affiliate faculty member in the Department of Aeronautics and Astronautics and is the Director of Modern Aircraft Structures Certificate Program at the University of Washington. He graduated from the University of California (Berkeley) with a BS and MS and from University of Washington with a PhD in Civil Engineering with focus in Structures Engineering. He was also a post doc for 2 years doing research in Failure Analysis at the University of Washington. He has published numerous papers and developed and taught many courses in aircraft structures at Boeing, DoD, airlines, suppliers, and MROs. He was the lead author for the chapter on Subsonic Aircraft Materials in AIAA’s book on Aerospace Materials published in 2017.
