Michel Duguay was born in Montréal on September 12, 1939. Education: BS in physics at the University of Montreal in June 1961, Ph.D. in Physics (thesis in nuclear physics) from Yale University in Connecticut in 1966.

Hired by AT & T Bell Telephone Laboratories in 1966 he changed his field to work in opto-electronics, particularly in laser physics and semiconductors. From 1974 to 1977 he was delegated by Bell Labs to work at Sandia National Labs in Albuquerque, New Mexico. His research at Sandia involved X-ray lasers and the lighting of building interiors using waveguides for sunlight.

In 1977, back at Bell Labs, Duguay began research on semiconductor lasers pumped by picosecond laser pulses. Duguay and his colleague Ted Damen demonstrated that semiconductor lasers are capable of generating pulses of less than one picosecond and can produce the laser effect over very large bandwidths.

Subsequently, Duguay and his colleagues at Bell Labs Holmdel discovered a new type of waveguide called “ARROW”, an acronym for Anti-reflecting Resonant Optical Waveguide. This discovery has resulted in a large number of experiments in the world on devices involving the ARROW phenomenon.

Michel Duguay joined Laval University in 1988 as holder of an industrial chair sponsored by Quebec Téléphone in Rimouski and by the Natural Sciences and Engineering Research Council (NSERC) in Ottawa. Duguay worked at Laval on optical communications, solar energy, the thermal storage of energy, and a new conceptual approach to space-time in special relativity, the so-called “diachronic time” approach. This diachronic time approach offers an original solution to the twin paradox in special relativity and the Einstein-Podolsky-Rosen effect in quantum optics. Twenty-five students have obtained a master’s or doctorate degree under the direction or co-direction of Professor Duguay. During his career Duguay has published 75 articles and obtained 30 patents.

Since 2005 Michel Duguay has been active in the movement to prevent the reconstruction of the Gentilly-2 nuclear reactor. He was the coordinator of the Let’s Move Quebec out of Nuclear movement. Duguay has well documented the case to justify the opposition to the reconstruction of the Gentilly-2 nuclear reactor.

Since May 2014, Professor Duguay has been involved in the movement to improve international security and to promote nuclear disarmament. In June 2016, he was invited to participate in a panel on armed drones held on the University of Toronto campus and organized by the group Science for Peace.

In Quebec City Duguay got involved in the question of the future of the Quebec Bridge. He was co-author of an article published in Le Soleil on July 7, 2016, and he published a letter about it in the Journal de Québec on September 3, 2016. Local newspapers have quoted Duguay’s work.

In the past three years Duguay has written a few articles on how to motivate people to support nuclear disarmament. He argues that the life sciences, especially the genetics and genomics branches, can bring to light a unifying concept by showing that all persons on Earth are part of the one human genome. In addition, including the human genome as part of one’s self-identity broadens the time scale of interest to about one million years. This attitude, when broadly adopted, will lower the influence of the widespread us/them mindset, and motivate people everywhere to collaborate on all issues.

Michel Duguay retired from Laval University in January 2020. He is an active member of Science for Peace and Canadian Pugwash. Seven of his articles are on the Science for Peace website.

Director: ELLEN JUDD

Ellen Judd is Distinguished Professor Emerita at the University of Manitoba and Visiting Professor of Anthropology at the University of British Columbia. Her research focuses on political anthropology, political economy, gender and human rights. Her ethnographic work is concentrated in studies of sociocultural change in contemporary rural and urban China. She was educated at Queen’s University, the University of British Columbia, Fudan University, Beijing University and the University of Cambridge, and has held visiting appointments at Sun Yatsen University, Chongqing University, Columbia University and the London School of Economics. She is the author of Gender and Power in Rural North China, a special issue of Anthropologica on War and Peace, and numerous other publications, most recently the co-edited Cooperation in Chinese Communities: Morality and Practice. In 2006 she was elected a Fellow of the Royal Society of Canada, and in 2012-13 she served as President of the Canadian Anthropology Society. Ellen Judd has been involved in the peace movement since the Vietnam War era and in the disarmament movement of the early 1980s while in England. More recently she has served on the Board of Project Peacemakers, the Winnipeg affiliate of Project Ploughshares, and on the National Board of Canadian Voice of Women for Peace. She has been increasingly concerned with the renewed arms race, escalating tensions on the Korean Peninsula and the US pivot to Asia. Continuing wider concerns with disarmament, she finds her scholarly research converging with her concern for peace. Her current direction draws upon China’s cultural politics, the legacy of China’s long century (1839-1949) of devastating war and the political economy of contemporary China to identify and examine resources for peaceful coexistence. She finds the Russell-Einstein Manifesto regrettably all too pertinent at the present time.

Director emeritus: METTA SPENCER; Professor emeritus of sociology, University of Toronto. She coordinated a program in peace and conflict studies at the Mississauga campus until retiring in 1997. She served several terms as president of Science for Peace. Professor Spencer’s introductory sociology textbook, Foundations of Modern Sociology, was published in ten editions in the United States and Canada and, according to one informed estimate, was read—at least in part—by over a million persons worldwide, mainly university students.
Another of her books, Two Aspirins and a Comedy: How Television Can Enhance Health and Society, explores the way serial dramas can sometimes create intense parasocial bonds with fictional characters that can influence a whole culture more powerfully than education or advertising. She advocates the development of well-crafted soap operas to improve a society’s prevailing ideology about war and politics. Spencer’s book, The Russian Quest for Peace and Democracy, was based on 28 years of interviewing prominent Soviet and Russian political figures, Eastern Europeans, and Western peace activists. Over 200 of the interview transcripts and many of the voice recordings are accessible at: RussianPeaceAndDemocracy.Com. She has also edited a number of other books on peace and conflict issues. See her web site Spencer is the founding and continuing editor of Peace Magazine. Most issues include transcripts of an interview with a prominent activist or influential person. See the archive at Peace Magazine is accessible by subscription in print or online:

In 2018 Spencer organized a two-day conference at the University of Toronto where 100 participants listed 25 proposals that would, if implemented, vastly reduce the risk of six grave global threats: war and weapons (especially nuclear); global warming; famine; pandemics; radioactive contamination; and cyber risks. This “Platform for Survival” could be adopted by many different activists as a common program. Intending to promote such adoption, Spencer has created a website,, as a meeting place for people working against these threats. It offers an events calendar for activists and researchers to publicize public activities anywhere in the world.

“Project Save the World,” has a Youtube channel, A series of educational videos are accessible 24/7. Several days each week, Spencer discusses current global issues with one or more experts. As of early November 2021 there are 368 one-hour-long shows in the series. People can post articles, comments, and replies about the shows, the six global threats, and three policy sectors of society: governance, economy, and civil society.
