Our collective work matters - thank you for standing with us

A message from Dr.Christopher Taylor, Associate Vice-President, Equity, Diversity, Inclusion & Anti-Racism.
As we close out 2025, I want to speak plainly: equity, diversity, inclusion, and anti-racism are not optional. They are essential to the integrity of our institution and to the future we are building together.
Over the past challenging year, your support has allowed the Office of EDI-R to push beyond performative gestures and into real, systemic change.
Our 2025 Impact Report tells that story:
- We supported equity-deserving communities with resources and advocacy, because representation without power is not enough.
- We continued to create spaces for truth-telling and accountability through initiatives like the Table Talks Series, ensuring that conversations lead to action.
- We listened to the trans and non-binary community and defined our strategy for addressing the systemic issues they continue to face.
- We heard that many community members don’t know where to turn when harm occurs, so we launched targeted campaigns and roadshows to promote our response processes to reduce barriers to accessing help.
- We critically examined emerging and persistent issues and developed a series of complex infographics and accessible social-media content to educate, inform, and increase institutional capacity.
- We held more educational events as part of the Menstrual Equity Program to further destigmatize menstruation for all genders and provide access to reusable menstrual products.
- We supported and advised campus partners across multiple offices to ensure data was being used responsibly, while strengthening institutional understanding of accommodation processes and policy compliance.
- We saw a significant growth in our online and social media presence, extending the reach of our work and strengthening how communities connect with our office.
- We engaged with students in a meaningful way through the Student Ambassadors Program and student-driven consultations, whose insights on belonging, safety, food security, and cultural wellbeing are now shaping our priorities for the year ahead.
- We opened our doors more intentionally to communities off-campus, strengthening our role within the ݮƵ region while building stronger bridges between on-campus and off-campus communities.
This work is political because equity work is about power: who has it, who doesn’t, and how we redistribute it to create justice. And let me be clear: we are not slowing down.
In 2026, we will:
- Deepen our engagement with communities—not as a checkbox, but as co-creators of institutional change.
- Hold ourselves accountable through transparent reporting and policy reform that moves beyond rhetoric.
- Expand education and capacity building, equipping our campus to lead courageously in a world that demands more than neutrality.
We are kicking off the year by launching a series of community resources designed to empower campus and local communities to lead projects that matter most to them. These initiatives aim to reduce financial barriers, support community-led solutions, and strengthen relationships with communities that we are connected to.
As I often say,“Equity work is not charity—it’s justice. And justice requires courage, persistence, and community.”
Our roots are in community. Our vision is bold. And our commitment is unwavering. But this work cannot happen in isolation: It requires all of us.
Thank you for standing with us. Thank you for believing that equity and justice are not just ideals. They are actions. Together, we will keep moving forward.

Craig Kaplan named 2025 ACM Distinguished Member

Looking for an academic who juggles computer graphics, mathematics and art (as well as chalk) seamlessly? Dr. Craig Kaplan's your guy!
This is an excerpt of .
The Association for Computing Machinery has named Professor Craig S. Kaplan ain recognition of his pioneering contributions to the design and modelling of computational geometric patterns and non-photorealistic rendering. He is amonghonoured this year for outstanding scientific achievements in computing.
“Congratulations to Craig on this much-deserved recognition from ACM,” said Raouf Boutaba, University Professor and Director of the Cheriton School of Computer Science. “This honour is his fourth major accolade in 2025, recognizing his teaching and research excellence. Earlier this year, he received the Faculty of Mathematics Award for Distinction in Teaching, was named a Fellow of the Fields Institute, and his co-discovery and proof of the first aperiodic monotile was cited by Sir David Spiegelhalter inBBC Science Focusmagazine as the most important mathematical breakthrough of this century.”
Professorjuggles a range of interdisciplinary topics with ease, working at the intersection of mathematics, computer graphics and art. He develops mathematical tools and algorithms that generate ornamental patterns and support artists and designers.
His work frequently incorporates knowledge from computer graphics, classical and computational geometry, human–computer interaction, graph theory, symmetry and tiling theory, and perceptual psychology. He holds the, a prestigious award that supports his research program.
Professor Kaplan’s research, teaching and service excellence
Solving the long-standingeinstein problem
Professor Kaplan’s most celebrated accomplishment is his 2023 co-discovery and proof of the first aperiodic monotile. Known asthe hat, the 13-sided polygon fills the infinite plane without gaps or overlaps in a pattern that cannot repeat. Its discovery resolved the famousor “one stone” problem in tiling theory, an open question for more than six decades.
Professor Kaplan’s involvement began when David Smith, a mathematical hobbyist, contacted him about a promising shape with seemingly aperiodic properties. Together with collaborators Joseph Samuel Myers and Chaim Goodman-Strauss, the team solved theeinsteinproblem and published their proofs in a paper titled “” inCombinatorial Theory. Shortly thereafter, the research team published “,” a paper in which they proved that a related family of shapes, calledspectres, tile the plane aperiodically using only translations and rotations, satisfying an even stricter definition of aperiodicity.
The discovery captured global attention. Media outlets includingThe New York Times,The Guardian,CNN,New Scientist,Smithsonian Magazine,Quanta MagazineandScientific Americancovered the breakthrough extensively.TIMEmagazine later named the hat as one of the best inventions of 2023, highlighting it alongside advancements in supercomputing, entertainment technology and materials science.
The public celebrated the discovery through online discussions, creative experimentation, and events such as, a conference held at the University of Oxford’s Mathematical Institute. As co-discoverer Chaim Goodman-Strauss reflected, “People made this their own… It’s absolutely unique, in my experience, for a mathematical result to have a cultural life like that.”
In the January 2025 issue ofBBC Science Focusmagazine spotlighting the game-changing breakthroughs shaping the world since the year 2000, Sir David Spiegelhalter described the solution to theeinsteinproblem as “the most important mathematical breakthrough of this century.” Aperiodic monotile enthusiasts continue to explore the shape ascreated by Sir David Spiegelhalter himself.
Impossible solids: Insights that helped elucidate molecular structure
The five Platonic solids and 92 Johnson polyhedra have long fascinated mathematicians. While exploring them, Professor Kaplan became intrigued by what he called “near misses,” geometric oddballs tantalizingly close to being a mathematically perfect solid. He documented many of these polyhedra on his website, including a structure built from 11-sided polygons, equilateral triangles and squares.
Years later, a. The molecular cage, formed from TRAP rings and bonded together with gold atoms, mirrored the structure of a near-miss solid Professor Kaplan had documented on his site and built using paper shapes and tape. Through a computational analysis of the stability of the TRAP-cage, Professor Kaplan helped the research team confirm that the protein’s molecular structure was physio-chemically possible. The resulting interdisciplinary study was published inNatureas “.”
Geometric patterns in art and design
Professor Kaplan has long held an interest in computer-generated Islamic geometric patterns, a field that he leads. His paper with David Salesin, “,” is the definitive work on the topic and has influenced both academic understanding and practical implementation of these patterns.
He has also made fundamental contributions to non-photorealistic rendering and geometric pattern generation. In particular, his paper with David Salesin titled “,” presented at SIGGRAPH 2000, helped draw the two fields closer together. He remains a sought-after reviewer in this research area and continues to explore the artistic and mathematical potential of decorative tilings, particularly in the style of M.C. Escher.
Professor Kaplan has developed a wide range of computational techniques to create, manipulate and analyze decorative patterns in computer graphics. His research with his students on, presented at SIGGRAPH 2007, introduced innovative graphical and combinatorial algorithms to design mazes based on images. And his work onintroduced an algorithm that takes an arbitrary image and automatically generates the corresponding optical art composition.
More recently, he and his students have expanded digital tools for artistic abstractions with new techniques to pixelate vector line art, synthesize geometric patterns and, a traditional artistic method to produce tonal and shading effects. These contributions have expanded the techniques available for artistic rendering in computer graphics.
Professor Kaplan has been commissioned to create designs for various contexts including book covers, furniture, theatre productions, and architectural elements. Hiswere featured in an exhibition at the Museum of Modern Art in New York, and hishave been incorporated into architectural installations at the National Museum of Mathematics.
