Congratulations to Dr. Yu-Ru Liu, professor of Pure Mathematics and director of the Women in Mathematics Committee (WiM), on her receipt of the 2026 Canadian Mathematical Society Krieger-Nelson Prize.
Awarded since 1995, the prize recognizes “outstanding research by a mathematician who identifies as a woman.” It is named for Dr. Cecilia Krieger – the first woman to receive a doctorate in mathematics from a Canadian university – and Dr. Evelyn Nelson, a brilliant Canadian mathematician who served on the CMS Board of Directors prior to her premature death at age 43.
“I am truly honoured by this recognition and sincerely appreciate the support of my colleagues who made it possible,” Liu says. “I am also deeply grateful to my teachers and mentors at every stage of my career, whose guidance and generosity have shaped my development and from whom I have learned so much.”
The award primarily recognizes Liu’s research on number theory, in which she applies analytic techniques – including the circle method and sieve methods – to study Diophantine problems. It also acknowledges her contributions in teaching, mentorship and community service, including her work with Women in Mathematics.
“Through her vision, energy, and generosity, she has shaped the next generation of mathematical talent in Canada and internationally,” says the press release from the CMS.
Liu feels fortunate to be part of the Pure Mathematics Department, where she has had the chance to work alongside first-rate students and highly supportive colleagues. She is also grateful for the opportunity to collaborate with many dedicated WiM faculty and students, whose commitment to fostering a more inclusive mathematical community she genuinely values and respects.
“I would like to express my heartfelt gratitude to Alfred Menezes, Jason Bell and other letter writers for their strong support,” Liu says. “I would also like to thank the Math Research Office, who first informed me about this prize. Finally, I would like to thank Anita Layton and Penny Haxell for the nomination. It is a great honour to follow in their footsteps.”
