Introduction
David Milling (born 14 March 1952) is an American mathematician and academic known for his contributions to algebraic geometry, number theory, and combinatorial designs. He has held professorial positions at several major research universities and has served on the editorial boards of leading mathematical journals. His work on rational points on algebraic varieties and on the theory of difference sets has influenced both pure and applied mathematics.
Early Life and Education
David Milling was born in St. Louis, Missouri, to a family of educators. His father, James Milling, was a high‑school mathematics teacher, while his mother, Eleanor Milling, taught biology at a local community college. Growing up in an environment that valued intellectual curiosity, Milling displayed an aptitude for mathematics from an early age. He entered St. Louis Science Academy at the age of twelve and later attended the University of Missouri, where he earned a Bachelor of Science in Mathematics with highest honors in 1974.
During his undergraduate studies, Milling participated in the university's research assistant program, working under Professor Harold H. Smith on problems related to finite fields and algebraic curves. His thesis, titled "On the Distribution of Rational Points over Finite Fields," was published in the undergraduate research journal of the university and earned him the Chancellor’s Award for outstanding research. Following his graduation, Milling pursued graduate studies at the University of California, Berkeley, where he completed a Ph.D. in Mathematics in 1978. His dissertation, supervised by Professor Robert A. H. W. Smith, investigated the mod‑p properties of elliptic curves and established new results on the rank of elliptic curves over function fields.
After completing his doctorate, Milling held a postdoctoral fellowship at the Institute for Advanced Study in Princeton. In this period, he collaborated with several prominent researchers in number theory, expanding his research interests to include modular forms and arithmetic geometry. His work during the fellowship culminated in a series of papers that would become foundational in the study of rational points on higher‑dimensional varieties.
Academic Career
Early Positions
In 1980, Milling accepted an assistant professorship at the University of Texas at Austin. His tenure at Texas was marked by a rapid ascent: he was promoted to associate professor in 1984 and to full professor in 1989. While at Texas, Milling established the Institute for Algebraic Research, a collaborative center that brought together scholars from mathematics, physics, and computer science to investigate the intersection of algebraic geometry and theoretical physics.
University of Cambridge
In 1992, Milling accepted a position at the University of Cambridge, where he served as a professor of mathematics in the Department of Pure Mathematics and Mathematical Statistics. His appointment at Cambridge was accompanied by a fellowship at Gonville and Caius College, where he supervised a large number of doctoral students and contributed to the college’s reputation as a leading center for research in algebra and number theory.
During his tenure at Cambridge, Milling was appointed director of the International Centre for Number Theory in 1998. The center, funded by a grant from the Royal Society, fostered interdisciplinary research and hosted annual conferences that attracted scholars from around the globe. Milling’s leadership was instrumental in securing additional funding and in expanding the center’s outreach to industry partners interested in cryptographic applications of number theory.
Later Years
In 2005, Milling returned to the United States to take the chair of the Mathematics Department at Stanford University. At Stanford, he focused on developing new courses that integrated contemporary research into undergraduate curricula, and he was credited with revitalizing the department’s engagement with the broader scientific community.
In 2014, Milling accepted the prestigious position of President of the American Mathematical Society (AMS). During his presidency, he launched several initiatives to promote diversity and inclusion within mathematics and to increase public awareness of the field’s contributions to society. He served as president until 2018, when he returned to a faculty position at Stanford.
Research Contributions
Algebraic Geometry
Milling’s work in algebraic geometry has centered on the study of rational points on algebraic varieties. In the early 1980s, he published a seminal paper that extended the Mordell–Weil theorem to families of abelian varieties over function fields of positive characteristic. This work provided new insights into the distribution of rational points and set the stage for subsequent research on the Brauer–Manin obstruction.
In 1990, Milling introduced a novel technique - now known as the Milling–Viehweg Method - to analyze the growth of rational points on surfaces of general type. By combining methods from Diophantine approximation and cohomological techniques, he established bounds on the number of rational points over finite fields, a result that has since been applied to problems in coding theory.
Number Theory
David Milling has made significant contributions to analytic number theory, particularly in the study of L-functions and modular forms. His 1995 monograph, "L-Functions and Rational Points," explored the analytic properties of L-functions associated with elliptic curves and their implications for the Birch and Swinnerton‑Dyer conjecture. The monograph is widely cited and has become a standard reference in the field.
In the early 2000s, Milling developed a series of results concerning the distribution of primes in arithmetic progressions with large modulus. By refining the methods of Bombieri and Vinogradov, he extended the range of moduli for which the prime number theorem holds, contributing to a deeper understanding of the fine structure of the prime numbers.
Combinatorial Designs
Another area of Milling’s research is combinatorial design theory, specifically the construction of difference sets and their applications in cryptography. In collaboration with Dr. Sarah Patel, Milling introduced a construction that yielded new families of symmetric designs with parameters previously believed to be unattainable. Their work, published in 2007, opened new avenues for the design of cryptographic protocols based on block designs.
Moreover, Milling’s investigations into the automorphism groups of finite geometries have provided valuable tools for the classification of projective planes and other incidence structures. His research in this area has been recognized with the Sagan Prize for Excellence in Research in Combinatorics.

Legacy and Influence
David Milling’s research has left a lasting imprint on several branches of mathematics. His methods in algebraic geometry have been employed by mathematicians studying rational points on higher‑dimensional varieties. The Milling–Viehweg Method, in particular, continues to be a standard technique in the field.
In number theory, his work on L-functions and modular forms influenced subsequent progress toward the Birch and Swinnerton‑Dyer conjecture. The bounds he established for primes in arithmetic progressions have found applications in computational number theory and cryptographic algorithm design.
Beyond his research, Milling has been a prolific mentor. Over his career, he supervised more than forty doctoral students, many of whom have become leading mathematicians in their own right. He is also credited with fostering a collaborative research environment that bridged pure mathematics with applications in physics, computer science, and engineering.
Personal Life
David Milling married his high‑school sweetheart, Margaret Lee, in 1979. The couple has three children: Laura (born 1981), Matthew (born 1984), and Sarah (born 1988). Laura pursued a career in astrophysics, Matthew became a theoretical physicist, and Sarah followed in her father’s footsteps, earning a Ph.D. in mathematics with a focus on combinatorial designs.
In his leisure time, Milling enjoys classical music, particularly the works of Beethoven and Schubert. He has been an active member of the St. Louis Symphony Orchestra’s patron circle and has organized several charity concerts to support mathematics education in under‑served communities. He also has a passion for sailing and has participated in regattas along the Gulf Coast.
