Notable Technical Inquiry

What efforts are now being performed to advance the state of the art in scramjet technologies?

A DSIAC subject matter expert from the Johns Hopkins University Energetics Research Group performed open-source and Joint Army Navy NASA Air Force (JANNAF) repository searches. The U.S. Air Force (particularly, the Air Force Research Laboratory [AFRL] at Wright Patterson Air Force Base [AFB], OH, and AFRL at Edwards AFB, CA), Defense Advanced Research Projects Agency, and National Aeronautics and Space Administration (NASA) all have and/or currently support programs to further the state of the art for hypersonic and scramjet technologies.…

Douglas M. Ray, PStat

Mathematical Statistician, U.S. Army CCDC Armaments Center

My work focuses on applying industrial statistics to the U.S. Department of Defense (DoD) armament systems across the acquisition life cycle for the Warfighter. This work includes design of experiments, reliability data analysis, machine learning, and uncertainty quantification/probabilistic optimization of computational models and simulations. I also led a group of over a dozen statisticians and data scientists who collaborate with engineering and business teams on a spectrum of armament projects and systems. In addition to my 13 years of experience as a DoD mathematical statistician, I am also a retired combat veteran of the U.S. Army. I hold a B.S. in applied mathematics from the University of Rhode Island and an M.S. in statistical engineering from New Jersey Institute of Technology. I am currently a Ph.D. candidate in systems engineering at Stevens Institute of Technology, and a Systems Engineering Research Center doctoral fellow.
