David Elliott learned automatic control theory as a working applied mathematician at the Naval Ordnance Test Stations Underwater Ordnance Department (now part of USNOSC San Diego) 1955-69, and obtained Masters and Doctoral degrees with Navy support and Fellowships. His dissertation was the first to apply a differential geometric (Lie algebra) approach to stochastic dynamic systems, and his work on nonlinear control systems has been foundational.
After UCLA he moved to the Control Systems Science and Engineering Laboratory at Washington University, which became the well-known Dept. of Systems Science and Mathematics. Among his students were Nick Kalouptsidis ( University of Athens), Dirk Aeyels ( University of Gent), Riccardo Marino (University of Rome II), and W. P. Dayawansa (Texas Tech University).
He accepted a two-year pre-retirement sabbatical in 1992, becoming Professor Emeritus and moving to the Institute for Systems Research. There he continues to advise doctoral students and perform research in nonlinear systems.
