Stephen Engel

Steve was one of the original PHM pioneers beginning in early 1990s with an ARPA contract entitled “Just-In-Time Maintenance” that used neural networks to diagnose and predict failures in rotating machinery. He helped shape the PHM philosophy during the JSF concept development phase in the late 1990s, emphasizing model-based reasoning for diagnostics and the non-deterministic aspects of failure prediction. His seminal paper, “Prognostics, The Real Issues Involved With Predicting Life Remaining” (IEEE 2000), was a motivating factor for the DARPA Prognosis Program in 2003. Steve was the technical lead for the DARPA-Navy-Northrop Grumman Structural Integrity Prognosis System (SIPS) Program and its follow-on contracts from 2003 to 2012. As a technical fellow specializing in AI reasoning methods, machine learning and prognosis for the Northrop Grumman Corporation, Steve served as a principal investigator for several formational programs including the US Navy’s prognosis flight demonstrations, DARPA’s Survivability of Interdependent Systems, and the US Air Force’s foundational contracts for the Digital Thread and Digital Twin.
