‘A life of extraordinary consequence’ McMaster Community mourns Professor Juliet Daniel

“McMaster University is mourning the loss of Distinguished University Professor and proud Barbadian-Canadian Juliet Daniel. “My friend Professor Juliet Daniel lived a life of extraordinary consequence,” says McMaster Chancellor Nicholas Brathwaite. “She was a world-class researcher and a trailblazer who led with both her heart and her mind. Her contributions to cancer research were monumental, yet she never lost her profound warmth or her commitment to her Caribbean roots. “While we mourn her passing, we celebrate a legacy that will endure through every life she touched and every student she inspired to dream bigger.” Daniel was internationally recognized for her pioneering research on Triple Negative Breast Cancer (TNBC), an aggressive cancer that disproportionately affects Black and Hispanic women. Her groundbreaking discovery of Kaiso, a gene whose malfunction leads to human developmental disorders or cancer, was heralded as the “missing piece of the breast cancer puzzle”. A graduate of Queen’s University and the University of British Columbia, Daniel joined McMaster as an assistant professor in November 1999, becoming the first Black woman faculty member in the Faculty of Science and one of the few Canadian researchers studying cancer health disparities at the molecular genetic level. “Juliet’s death is a tragedy that affects many people and communities across the Caribbean and in Canada, and our community here at McMaster is profoundly saddened,” says McMaster President and Vice-Chancellor Susan Tighe. “The depth of our collective grief reflects her far-reaching and positive influence. Like so many, I admired her humanity, her skill and her strength. It genuinely seemed like she could do anything she put her mind to.” “Juliet’s legacy is immense — as a scientist, as a powerful and effective advocate for equity and inclusion, and as an example of achievement who inspired her colleagues and students alike.” Juliet Daniel surrounded by student researchers in her lab in 2019. (Jamie Kaushal, Faculty of Science) Daniel established a research group at McMaster to identify genetic risk factors that could explain the prevalence and high mortality associated with TNBC in women of African ancestry. Her research group demonstrated that the gene she discovered plays a role in the proliferation and survival of TNBC cells. Daniel’s research, funded by national and international agencies, has been cited more than 4,000 times. In 2024, she was one of three Canadian scientists to be named a Black Innovator in Research and Medicine by the Government of Canada’s Canadian Intellectual Property Office. Daniel also served in key senior leadership roles, first as the Associate Dean of Research & External Relations in the Faculty of Science and then as Strategic Advisor to the President for the Canada-Caribbean Institute at McMaster. “Not only was Juliet a brilliant researcher, she was also a fierce advocate for her community and an inspiring mentor for her students,” says McMaster President Emeritus David Farrar. “Together with the President’s Office, she organized the first Canadian scientific meeting of the Canadian Caribbean Institute, bringing together researchers, political leaders and community activists to address critical issues in climate and energy policy. “She was a force. She believed passionately that universities have an immense role and responsibility to improve people’s lives everywhere, and she lived that belief through her own research and community organizing.” In 2025, Daniel was named a Distinguished University Professor, McMaster’s highest honour for faculty members who have made a significant and lasting impact on the university, their respective fields and society at large. Daniel was also elected to the Canadian Academy of Health Sciences, considered one of the highest honours for individuals in the Canadian health sciences community. Beyond her research as a cancer biologist, Daniel was committed to improving equity, diversity and inclusion in higher education. She was co-founder of the Canadian Black Scientists Network, the McMaster Academic Women’s Success and Mentorship Lecture Series and the Canadian Multicultural LEAD Organization for Mentoring and Training, and was proud of her foundational work with the President’s Advisory Committee on Building an Inclusive Community, or PACBIC. Daniel was a co-founder of the African Caribbean Faculty Association of McMaster (ACFAM) and played a foundational role in shaping both the association and the community it represents today. Her vision helped establish ACFAM as a space of solidarity, support and collective action, and she was also instrumental in advancing broader initiatives at McMaster, including the Black faculty cohort hire and efforts supporting Black student success.

For us, Juliet was more than a colleague; she was a friend, confidant, collaborator, and someone who showed up consistently with care and conviction in her fierce advocacy for all. Her leadership helped build community not only among Black faculty, staff, and students, but across the institution more broadly. She will be dearly missed.” In recognition of her research excellence and leadership, Daniel received international awards and honours, including a Black Excellence in STEM & Medicine (BE-STEMM) Mentorship Award from the Canadian Black Scientists Network, an Honorary Doctor of Science and Vice-Chancellor’s Award from the University of the West Indies, a WXN Canada’s Most Powerful Women: Top 100 Award, a Harry Jerome Innovation & Technology Award from the Black Business and Professionals Association, a Hamilton YWCA Women of Distinction Award, an Illuminessence Legacy of First Award, the Errol Walton Barrow Award of Excellence from Barbados Ball Canada Aid, the Barbados Gold Crown of Merit, the Ontario Premier’s Research Excellence Award, the John C. Holland Professional Achievement Award and the African Canadian Achievement Award of Excellence in Science. Daniel passed away on April 28, surrounded by family and friends. She was 61 years old. McMaster University will lower its flags in remembrance of Daniel at a future date, to be determined in consultation with her estate.
