The text has been adopted in several undergraduate programs, illustrating Su’s impact on how mathematics is taught at the national level.

Leadership and Service to the Mathematical Community

Su’s influence extends well beyond his home institution. He has held several high‑profile leadership positions that have shaped the direction of mathematics in the United States.

• President of the Mathematical Association of America (MAA), 2015–2017: As the chief executive of the MAA, Su oversaw initiatives aimed at improving undergraduate mathematics education, expanding outreach, and fostering a sense of community among mathematicians. His tenure emphasized the importance of mathematical thinking as a tool for civic engagement and personal growth.

• Vice‑President of the American Mathematical Society (AMS), 2020–2023: In this role, Su contributed to the governance of one of the world’s largest societies dedicated to advancing research and scholarship in mathematics. His service helped guide policy decisions, support research dissemination, and promote diversity within the discipline.

Su’s leadership has also been recognized through scholarly honors. He served as a Phi Beta Kappa Visiting Scholar during the 2019–2020 term, delivering lectures that highlighted the connections between mathematics, beauty, and human flourishing. Moreover, in 2025 he was elected a Fellow of the American Mathematical Society, an accolade reserved for members who have made outstanding contributions to the creation, exposition, advancement, communication, and application of mathematics.

Research Focus: Combinatorics and Fair Division

Su’s research interests lie primarily in combinatorics, the branch of mathematics that studies discrete structures, counting, and the arrangement of objects. Within this broad field, he has become especially known for his work on fair division, a subarea concerned with allocating resources among individuals in a way that is perceived as equitable by all parties.

Fair division problems have deep historical roots, ranging from the classic “cake‑cutting” paradoxes to modern applications in economics, political science, and computer science. Su’s contributions have helped formalize notions of fairness, develop algorithms that achieve proportional or envy‑free allocations, and articulate the philosophical underpinnings of why fairness matters in both mathematical theory and everyday life.

His research blends rigorous proof techniques with an eye toward real‑world relevance, reflecting the influence of his doctoral advisor Persi Diaconis, who similarly bridges pure and applied perspectives. While specific theorems and papers are beyond the scope of this article (as the source does not enumerate them), Su’s reputation in the fair‑division community is widely acknowledged and has inspired subsequent generations of scholars to explore equitable algorithms in diverse settings.

Writing for a General Audience

Beyond technical research articles, Su has devoted considerable effort to communicating mathematics to broader audiences. His most celebrated popular‑science work is the book Mathematics for Human Flourishing, released on 7 January 2020. The book expands on a speech of the same title delivered on 6 January 2017 at the Joint Mathematics Meetings, one of the largest annual gatherings of mathematicians worldwide.

In the speech—and subsequently the book—Su argues that mathematics is not merely a collection of abstract symbols but a language that can nurture curiosity, creativity, and ethical reflection. He emphasizes that mathematical thinking equips individuals to make better decisions, appreciate beauty, and engage responsibly with societal challenges.

The speech earned the Halmos‑Ford Award for Distinguished Writing in 2018, recognizing excellence in expository writing that makes mathematics accessible and inspiring. Moreover, three of Su’s articles have been selected for inclusion in The Princeton Anthology of the Best Writing in Mathematics (2011, 2014, and 2018), a curated collection that showcases the most compelling mathematical essays of each year.

In 2021, Su’s collaborative effort with Christopher Jackson was honored with the Euler Book Prize, awarded jointly by the MAA for books that convey the beauty and utility of mathematics to a wide readership. This accolade underscores Su’s ability to bridge scholarly rigor with popular appeal.

1. Inquiry‑Based Learning – Through works like Topology Through Inquiry, he advocates for pedagogical models that empower students to discover concepts themselves, fostering deeper comprehension and a sense of ownership over knowledge.

1. Interdisciplinary Dialogue – Su frequently engages with scholars from philosophy, economics, and the arts, emphasizing that mathematical reasoning can enrich conversations across domains.

1. Community Building – His leadership roles in the MAA and AMS reflect a commitment to cultivating inclusive, supportive professional communities where diverse voices are heard.

These ideas have resonated with educators, policymakers, and the general public, encouraging a view of mathematics as a collaborative, humane enterprise.

Relevance to Apiary’s Mission

While Francis Su’s primary domain is mathematics, several aspects of his work align indirectly with Apiary’s focus on cooperative systems and ethical AI.

• Fair Division Algorithms: The mathematical foundations of equitable resource allocation are directly applicable to designing AI agents that negotiate, share, or distribute resources without bias.

• Human‑Centric Design: Su’s emphasis on flourishing underscores the importance of building technological systems—such as self‑governing AI—that prioritize human well‑being.

• Community Governance: His experience in leading professional societies offers valuable insights into how decentralized, self‑governing structures can function effectively, a principle that parallels Apiary’s vision for autonomous AI collectives.

Thus, while Su is not a bee‑conservationist, the ethical frameworks he champions can inform the development of responsible AI ecosystems that respect fairness and communal health.
