Saturday, May 15, 2021

It is with great sadness that we note the passing today of Charlie Doering. A friend to many, a mentor to a lucky group of students, postdocs and younger colleagues, and a treasured colleague across many disciplines, Charlie leaves an amazing legacy of scientific excellence, professional integrity, and personal warmth and charm. He had a profound influence on the Center for Nonlinear Studies, first as an eager and productive postdoc, then and later as a frequent visitor, and for an all too brief time as the CNLS Deputy Director during a time of great uncertainty when his presence made all the difference. Even after leaving CNLS for the University of Michigan, Charlie always held CNLS in the highest regard, attending many conferences and visiting often; his latest CNLS Colloquium was in December 2020. His boundless energy and enthusiasm, his scientific acumen, and his wisdom and charm will be missed by many. We keep in our thoughts his family and friends during this difficult time.

Robert Ecke, Director Emeritus, CNLS

What is CNLS?

The Center for Nonlinear Studies (CNLS) is part of the Laboratory's Theoretical Division, and it organizes research related to nonlinear and complex systems phenomena. CNLS was formed in October of 1980.

CNLS Mission Statement

  • Identify and study complex nonlinear phenomena using a diverse set of research approaches and methodologies, particularly those of statistical physics, nonlinear science, applied mathematics and numerical simulation.
  • Promote the use of scientific results in applied research.
  • Stimulate the formation of interdisciplinary approaches to complex problems.
  • Facilitate the interchange of scientific results and ideas between Laboratory scientists and external centers of excellence.
  • Encourage the exploration of new scientific frontiers at the interface between conventional disciplines.
  • Support a broad spectrum of interdisciplinary science that underpins the Laboratory's mission in national security.
