Donna Strickland

Lore & Background

Strickland was born on May 27, 1959, in Guelph, Ontario, Canada to Edith J. (née Ranney), an English teacher, and Lloyd Strickland, an electrical engineer. After graduating from Guelph Collegiate Vocational Institute, she attended McMaster University, graduating with a Bachelor of Engineering degree in engineering physics in 1981. She earned her Doctor of Philosophy degree in 1989 from The Institute of Optics at the University of Rochester, conducting doctoral research at the Laboratory for Laser Energetics under Gérard Mourou.

Strickland and Mourou developed an experimental setup to raise the peak power of laser pulses, overcoming a limitation where self-focusing damaged the amplifying part of the laser. Their 1985 technique of chirped pulse amplification stretched each laser pulse spectrally and in time before amplifying it, then compressed it back to its original duration, generating ultrashort optical pulses of terawatt to petawatt intensity. This work received the 2018 Nobel Prize in Physics.

From 1988 to 1991, Strickland was a research associate at the National Research Council of Canada, working with Paul Corkum in the Ultrafast Phenomena Section. She worked at Lawrence Livermore National Laboratory from 1991 to 1992, joined Princeton University's Advanced Technology Center for Photonics and Opto-electronic Materials in 1992, and joined the University of Waterloo in 1997 as an assistant professor, becoming the first full-time female professor in physics there. She is currently a professor, leading an ultrafast laser group.

Reader's Guide

Donna Strickland's significance lies in her co-invention of chirped pulse amplification, a technique that enabled the generation of ultrashort, high-intensity laser pulses. This breakthrough, published in 1985 while she was a doctoral student, overcame the limitation of self-focusing damage in lasers and allowed the construction of table-top terawatt lasers. The technique has widespread applications, including laser micromachining, laser surgery, medicine, and corrective laser eye surgeries. Strickland became the third woman ever to be awarded the Nobel Prize in Physics, after Marie Curie and Maria Goeppert Mayer. Her career includes roles at the National Research Council of Canada, Lawrence Livermore National Laboratory, Princeton University, and the University of Waterloo, where she became a full professor after her Nobel prize. She has served as fellow, vice president, and president of Optica, and is a member of several academies, including the Royal Society and the National Academy of Sciences. Her legacy includes the Natural Sciences and Engineering Research Council of Canada Prize being set in her name.

Did You Know?

• She described herself as a 'laser jock' because experimentalists need to understand physics and make things work.
• She became the first full-time female professor in physics at the University of Waterloo.
• Strickland and Mourou published their pioneering work 'Compression of amplified chirped optical pulses' in 1985.

The 2018 Nobel Prize and an Unequal Footing

In 2018, physicist Donna Strickland was awarded the Nobel Prize in Physics, a recognition that placed her among the most distinguished scientists of her generation. Yet the circumstances surrounding her achievement carried an uncomfortable parallel that would later be cited as a defining example of systemic gender bias in knowledge documentation. While Strickland shared the Nobel Prize with two male colleagues, both men already possessed dedicated Wikipedia biography articles at the time of the announcement. Strickland, by contrast, had no such page. This disparity was not an oversight in the Nobel committee's selection process but rather a reflection of a broader pattern in which women's professional accomplishments went unrecorded in one of the world's most widely consulted reference sources. The fact that a Nobel laureate in physics could lack a basic encyclopedic entry while her co-recipients did not underscored how deeply embedded the gap was, even at the highest levels of scientific recognition.

The Rejection That Sparked a Movement

Before her Nobel Prize brought global attention, Donna Strickland's attempt to secure a Wikipedia biography had been turned down. An editor reviewing her proposed article concluded that the submitted references did not demonstrate that she met the threshold for a standalone encyclopedia entry. This rejection became a frequently cited illustration of the gender imbalance that plagued Wikipedia's coverage of scientists. Academic research published in 2015, including a paper examining how women were systematically underrepresented in the encyclopedia's biographical content, had already documented this pattern. Strickland's case crystallized the problem for a new generation of volunteer editors who were building solutions. The Women in Red project, launched in 2015 by volunteer editor Roger Bamkin and subsequently joined by Rosie Stephenson-Goodknight and Emily Temple-Wood, explicitly pointed to examples like Strickland's to demonstrate that the absence of a woman's page was not a reflection of her qualifications but of a structural bias in who wrote and who was written about.

A Case Study in the Women in Red Project

Donna Strickland's pre-Nobel Wikipedia absence became one of the most cited examples within the Women in Red WikiProject, a volunteer initiative that began in 2015 to close the gender gap in encyclopedia coverage. The project's name is drawn from the red hyperlinks that appear in Wikipedia articles when a linked topic has no dedicated page yet. Conceived by Roger Bamkin, who initially called it Project XX before settling on the Women in Red title, the effort was joined by Rosie Stephenson-Goodknight and later by Emily Temple-Wood, whose personal practice was to draft a new article about a female scientist every time she faced harassment for her editing work. The project organized in-person edit-a-thons in cities worldwide and maintained a continuous virtual event, training new contributors to identify and create the missing biographies. Participants compiled lists of 150 red-linked articles to streamline the process of finding women who deserved entries. Strickland's story served as a rallying point, showing that even a Nobel-caliber physicist could be invisible in the world's largest free encyclopedia.

From One Missing Page to a Global Shift

The broader movement that Donna Strickland's case helped catalyze achieved remarkable scale. By December 2016, just over a year after the project's founding, Women in Red volunteers had contributed more than 45,000 new articles, nudging the share of English-language biographies devoted to women from 15 percent to 16.8 percent. Over five years, the project generated approximately 175,000 articles. By December 2024, the proportion of women's biographies on English Wikipedia had climbed to 20 percent. A study of biology faculty at top U.S. research universities found that the trend had reversed: in 2018, men were more likely to have a dedicated page, but by 2022, women biologists were, with nearly half of those entries written by Women in Red volunteers. The project also inspired spin-off edit-a-thons and entirely new WikiProjects. At Wikimania 2016 in Italy, Wikipedia co-founder Jimmy Wales named two of its core volunteers Wikipedians of the Year, and in 2026 the project was voted the Coolest Project of the previous 25 years.
