In Memoriam Caryl Johnson 1946-2019

With a 30-year career in science and science management, Dr. Johnson specialized in solving the challenges inherent in complex systems. At Introspective Systems, she directed the strategic science vision of the company and was the innovator behind xGraph, designed to solve her particular life lessons learned in building complex adaptive systems of systems.

Her early work with the computer automation of regional and global seismic networks established the standard for such systems worldwide, and in its current form serves as a core algorithm (GLASS associator) of global seismic network processing by the U.S. Geological Survey’s National Earthquake Information Center (NEIC) in Golden, Colorado.

She had over 50 scientific papers in reviewed professional journals and reference books and is the author of a popular book on volcanoes. She also spent 15 years overseeing cutting-edge R&D and systems design in the private sector and at BAE Systems as a Systems Engineering Fellow.

At BAE Systems she provided leadership and scientific direction to management and business area directors related to evolving DOD applications of computational intelligence and virtual systems engineering as applied to robotics, machine vision, sensor fusion, cognitive interface technology, and mission performance optimization.
