# Top Influential Mathematicians Today

Mathematics is very old. In fact, it dates back to the cradle of civilization, emerging out of the early societies in Ancient Egypt and Sumeria (modern day Iraq). Like our natural languages, the development of mathematics probably started for practical reasons, like keeping track of inventory and taxes. Keeping track means counting (and measuring), and to a large extent, the study of math is still rooted in numbers. But math is so much more.

Early Greek thinkers extended the Egyptian and Sumerian systems to the mathematics of shapes and places, with Euclid’s geometry. The Scientific Revolution brought us systems for describing rates of change—the calculus, developed by Enlightenment geniuses like Isaac Newton and Gottfried Leibnitz. Today, we have string theory, knot theory, and the abstract analysis of multi-dimensional shapes that would seem bizarre to the ancients (and to non-mathematicians today).

Mathematics has continually expanded into more and more powerful and abstract areas of study. Professional mathematicians understandably specialize, and only a few truly great mathematicians can honestly be said to understand most of the field. Yet, in the end, mathematics remains counting. The study of numbers (and numerical treatments of structures, shapes, and changes) is one of the most powerful fields of study—one of the central discoveries of all of humankind—that has made possible modern science and technology, from abstract physics to the blueprints for an iPhone or automobile. Math runs the world. And in this list, we’ll get introduced to the most influential—and brilliant—mathematicians in our modern world.

In what follows, we look at influential mathematicians over the last decade. Based on our ranking methodology, these individuals have significantly impacted the academic discipline of mathematics within 2010-2020. Influence can be produced in a variety of ways. Some have had revolutionary ideas, some may have climbed by popularity, but all are academicians primarily working in mathematics. Read more about our methodology.

**Note:** This isn’t simply a list of *the most influential mathematicians alive today*. Here we are focused on the number of citations and web presence of scholars in the last 10 years. There are other highly influential scholars who simply haven’t been cited and talked about as much in the last 10 years, whereas some new faces have been making a splash in the news, speaking events, and publishing, publishing, publishing. Our AI is time sensitive. To find some of the big names you might have expected to see here, we encourage you to use our dynamic ranking system and check influence over the past 20 and 50 years.

Those who know him are quick to point out that he has an impressive grasp of seemingly all of mathematics—a rare feat, particularly today in an age of specialization. He has also done important work in fields as diverse as probability theory to number theory. As fellow mathematician Timothy Gowers put it when reviewing one of Tao’s books, *“it is not easy to find gaps in Tao’s knowledge, and if you do then you may well find that the gaps have been filled a year later.”*

Tao has won numerous awards, including but not limited to the Field Medal (referenced above), in 2006 a MacArthur Award (the “genius” award), Fellow of the Royal Society (2007), and in 2009 he was inducted into the American Academy of Arts and Sciences.

## 10.Andrew Wiles

University of Oxford

Royal Society Research Professor

*Taniyama–Shimura Conjecture for Semistable Elliptic Curves, Fermat’s Last Theorem, Iwasawa Theory*

Wiles is Royal Society Research Professor at the University of Oxford. He became an overnight sensation when he proved one of the most famous conjectures in all of mathematics, known as Fermat’s Last Theorem, after the 17th century mathematician Pierre Fermat. Wiles received his bachelor’s degree in Mathematics from Oxford and his Ph.D. in Mathematics from the University of Cambridge. He spent a year at Princeton University’s Institute for Advanced Study and then became Professor of Mathematics at Princeton University. He has taught back and forth between Princeton and Oxford for much of his stellar career.

Wiles became interested in Fermat’s Last Theorem as a child of ten, he recalls, and his later professional career became a quest to find a proof of the famous centuries old conjecture in number theory. When he proved it true in 1993, not just the world of mathematics but the entire world and the media reported the accomplishment (technically, it wasn’t completely proved until 1994). Wiles thus enjoys status among mathematicians as having solved a problem many thought true, but essentially unprovable before him.

Not surprisingly, Wiles has received many honors and awards for his career in mathematics, including the Fermat Prize (no surprise), the Wolf Prize, and a Copley Medal. He was awarded a MacArthur Fellowship in 1997.

## 20.Roger Penrose

University of Oxford

Emeritus Rouse Ball Professor of Mathematics

*Mathematical Physics, General Relativity, Cosmology*

Penrose is Emeritus Rouse Ball Professor of Mathematics at the University of Oxford. He is also Emeritus Fellow of Wadham College, a constituent college of Oxford, and an honorary Fellow of Saint John’s College, Cambridge. Penrose received his bachelor’s in mathematics (first-class degree) from University College, London, and completed his Ph.D. at St. John’s College, Cambridge in 1958.

Along with the late Stephen Hawking, Penrose is one of a select few mathematicians (or mathematical physicists, in the case of Hawking) who are generally known and “famous.” Over his impressive career, Penrose has developed sophisticated mathematics to analyze Einstein’s “space-time,” contributing greatly to our understanding of fundamental physics. His exploration of mathematical singularities has expanded our understanding of core phenomena like the Big Bang and Black Holes. Penrose used advanced mathematics to develop a theory of how energy can be extracted from a Black Hole, now called the “Penrose process” in his honor. He is also known for his contributions to tiling theory, another area of mathematics dealing with shapes and topologies. He discovered the eponymous Penrose tilings in 1974. He is also known for Penrose Diagrams, causal diagrams connecting points in spacetime.

In addition to his ongoing and fundamental contribution to mathematics and mathematical physics, Penrose is a successful popularizer of difficult concepts in the sciences. His The Road to Reality: A Complete Guide to the Laws of the Universe, published in 2004 is a readable tour of the laws of physics for interested non-specialists. He is also known for his foray into the problem of consciousness (what is the nature of conscious experience?), writing two widely-read books on the subject, where he argues that consciousness arises from quantum events in the brain.

Penrose was elected a Fellow of the Royal Society in 1972. Among his many other accomplishments, he won the prestigious Eddington Medal with Stephen Hawking in 1975, and the Albert Einstein Medal in 1990. In 1994, Penrose was knighted for his outstanding service to science and mathematics.

## 21.Edward Witten

Princeton University Institute for Advanced Study

Professor of Mathematical Physics

*String Theory, Quantum Gravity, Supersymmetric Quantum Field Theory*

Witten is Professor of Mathematical Physics at Princeton’s Institute for Advanced Study (IAS). He is known world-wide for his many important contributions to the mathematics of string theory and treatments of theoretical physics. Interestingly, Witten received his Bachelor of Arts degree in History, with a minor in Linguistics at Brandeis University in 1971. After graduation, Witten wrote for The New Republic and The Nation, and even worked on George McGovern’s presidential campaign! He returned to college and studied economics at the University of Wisconsin-Madison before dropping out, returning to Princeton University to study applied mathematics, where he received his Ph.D. in Physics in 1976.

The rest, as they say, is history. Witten won the “genius award,” the MacArthur Grant in 1982, and had won the Fields Medal in Mathematics in 1990. Technically a physicist (not a mathematician), the noted mathematician Michael Atiyah noted that Witten’s “command of mathematics is rivaled by few mathematicians, and his ability to interpret physical ideas in mathematical form is quite unique.” Indeed, with Witten’s talent it is difficult to separate his thinking about theoretical physics with mathematics proper, as the “thinking” about physics is done in the language of mathematics. At any rate, Witten is widely regarded as one of the finest mathematicians in the world, as the Fields Medal surely attests.

Among many other awards, Witten received the Nemmers Prize in Mathematics in 2000.

## 22.James Maynard

University of Oxford

Research Professor

*Prime Gaps, Duffin–Schaeffer Conjecture*

James Maynard is a research professor at the University of Oxford, and was previously a postdoctoral researcher at the University of Montreal. He completed his bachelor’s and master’s degrees at University of Cambridge in 2009, and earned his Ph.D. at Oxford in 2013.

One of the youngest names among influential mathematicians, Maynard was just 26 when he came to prominence after providing a different proof to a popular theory of prime gaps at the time provided by Yitang Zhang. Indeed, Maynard is seen as a kind of specialist in prime gaps, and also solved a conjecture proposed by Paul Erdős concerning the topic. More recently, he helped prove the Duffin–Schaeffer conjecture.

For his work, Maynard has received several major awards, including the SASTRA Ramanujan Prize, the Whitehead Prize, the EMS Prize, and the Cole Prize in Number Theory.

Hungarian-born Peter Lax currently holds the title of Professor Emeritus at the Courant Institute of Mathematical Sciences at New York University. Lax began working at NYU in 1951; prior to that, he worked on the Manhattan Project.

Lax’s family emigrated from Hungary in 1941 while he was a teenager, and at 17 he was able to study for three semesters at NYU (where he wound up acting as an instructor). He was drafted into the U.S. army and allowed to take classes at Texas A&M University, though his studies were again interrupted when he was sent to work at the Oak Ridge National Laboratory, as well as the Manhattan Project (all before earning an undergraduate degree). He was finally able to return to NYU in 1946, earn his bachelor’s degree with pooled credits, and complete his PhD there in 1949.

As a mathematician, Lax is known for a wide body of work on partial differential equations, pure mathematics, fluid dynamics, shockwaves, and computing. In particular, Lax is famous for the “Lax conjecture” about hyperbolic polynomials, which he proposed in 1958, and which went unproven for over four decades.

Published works from Lax include Linear Algebra and Its Applications.

For his work, Lax has received numerous awards and honors, including membership with the Norwegian Academy of Science and Letters and the (American) National Academy of Sciences, as well as a Lester R. Ford Award, National Medal of Science, Wolf Prize, Abel Prize, and fellowship with the American Mathematical Society.

## 24.Barry Mazur

Harvard University

Gerhard Gade University Professor

*Diophantine Geometry, Generalized Schoenflies Conjecture, Mazur Swindle, Mazur’s Torsion Theorem*

Barry Mazur currently holds the title of Gerhard Gade University Professor at Harvard University, where he has worked as a professor since 1962. Prior to his long tenure at Harvard, Mazur held post-doctoral fellowships at Harvard and the Institute for Advanced Study. Mazur earned his PhD in Mathematics at Princeton University; though he attended MIT as an undergraduate, he did not complete a bachelor’s degree.

Mazur boasts a long career of discoveries and advancements in geometry, arithmetic, and number theory. In fact, he has several discoveries and proofs named after him, including the Mazur swindle, the Mazur manifold, and Mazur’s torsion theorem. Mazur is particularly famous for the latter, which was used by Andrew Wiles in his groundbreaking proof of Fermat’s Last Theorem.

Notable works from Mazur include Imagining Numbers and Prime Numbers and the Riemann Hypothesis.

For his work, Mazur has received awards and honors including membership with the American Philosophical Society, the Steele Prize, the Cole Prize, and the Veblen prize from the American Mathematical Society, as well as fellowship, and the Chauvenet Prize from the Mathematical Association of America.

Collège de France - IHES, Ohio State University

Emeritus Professor, Distinguished Professor

*Baum–Connes Conjecture, Noncommutative Geometry, Operator Algebras, Thermal Time Hypothesis*

Connes is currently Professor at the Collège de France, IHÉS, in France, as well as at Ohio State University and Vanderbilt University. Connes’ work focuses on algebra, or what is known as “operator algebra,” an important area in functional analysis. Born in France, Connes received his undergraduate degree in Mathematics from the prestigious École normale supérieure in Paris and his Ph.D. from the University Pierre et Marie Curie.

Among other notables, Connes was a member of Bourbaki, a group of predominantly French mathematicians who formed after the First World War in response to the loss of so many mathematicians in the wake of the war. The Bourbaki group (a pseudonym—there was no person “Bourbaki”) consisted of world-class mathematicians who contributed to mathematics by taking up the task of writing major new texts. Connes is also known for fundamental work in mathematics, such as the Connes embedding problem, a problem in algebra. He is also known for the Baum-Connes conjecture and has made important contributions to differential geometry.

Connes was awarded the Fields Medal in 1982. He is a member of the French Academy of Sciences as well as the US National Academy of Sciences (and others, including Danish, Norwegian, and Russian).
