CAIMS Research Prize Presented to Dr. Leon Glass

It is a great honor for the Canadian Applied and Industrial Mathematical
Society to present the Research Prize to Dr. Leon Glass from McGill University.
Dr. Leon Glass, a fellow of the Royal Society of Canada, has made seminal
contributions to research, education and community leadership.

His early research on dynamic genetic networks in the 1970’s and 80’s has laid
the foundation of major developments in systems biology. Through L. Glass’
work, tools from dynamical system theory became available for the analysis of
large genetic networks.

In collaboration with M Mackey, L. Glass studied delayed feedback control in
physiological systems. They found, for the first time, that chaotic dynamics
arise naturally in such  feedback systems. Their paper in Science from 1977
has more than 4000 citations and their model is now known as the Mackey-Glass
equation.

A special interest of L. Glass is the analysis and detection of cardiac
arrhythmias. He and his colleagues could show the existence of chaotic dynamics
in embryonic chicken heart cells, which was the first demonstration of chaotic
behavior in a biological system. J. Gleick wrote in his popular science book
“Chaos” about Glass that this was “one of the most talked about lines of
research in the whole short history of nonlinear dynamics” (1987). L. Glass’
research on cardiac arrhythmias culminated in patents for a detection software
of carciac arrhythmias.

L. Glass is a true interdisciplinary researcher, with publications in
mathematics, biology, and physiology journals. He educated students in all
these disciplines and guided them to fully interdisciplinary research. His work
is unique within our Society and his career is a role model for the next
generation of mathematical physiologists.
