Top Influential Computer Scientists Today

Computer science as an academic discipline is less than a hundred years old, but our fascination with mechanical devices and procedures dates back millennia. Today, computer science is a huge academic (and professional) discipline, as the modern world has embraced computing in every facet of life—from big data in physics laboratories to social media apps on ubiquitous smartphones. In what follows, we’ll look at the most influential people in the field of computer science today.

Top Influential Computer Scientists Today

Computer science as an academic discipline is less than a hundred years old, but our fascination with mechanical devices and procedures dates back millennia. The 9th century Persian astronomer and mathematician Muhammad bin Musa al-Khwarizmi is often credited with the invention of the algorithm, a key idea undergirding all of computing. But modern computing started with the groundbreaking work of British mathematician and code-breaker Alan Turing. Turing’s ideas about mechanical procedure, later known as “Turing Machines,” laid the theoretical groundwork for what was to come—digital computers, programming languages, and the modern world of the Internet and smart phone. Turing, truly, was the father of computer science.

By 1946, the world’s first programmable electronic computer, called the ENIAC, launched an arms race for ever more powerful computer hardware, and the study of computer programming and algorithms design was also in full swing. The first academic degree in the fledgling field of computer science, called the Cambridge Diploma in Computer Science, was awarded in 1953 by the University of Cambridge in England. The degree proved to be auspicious, as it was quickly recognized around the world, as work continued and expanded in earnest on computing in the United States, Europe, and elsewhere. Computer science quickly became a “hot” and important academic degree, particularly as personal computers arrived in the 1970s and 80s. Today, computer science is a huge academic (and professional) discipline, as the modern world has embraced computing in every facet of life—from big data in physics laboratories to social media apps on ubiquitous smartphones.

In what follows, we look at influential computer scientists over the last decade. Based on our ranking methodology, these individuals have significantly impacted the academic discipline of computer science 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 computer science. Read more about our methodology.

Tim Berners-Lee
(1955 -   )

Massachusetts Institute of Technology (MIT), University of Oxford

Professor & Professorial Fellow of Computer Science

HTML, Invented World Wide Web

Tim Berners-Lee (also called “TimBL” or “TBL”) is a Professorial Fellow of Computer Science at the University of Oxford and a professor at the Massachusetts Institute of Technology (MIT). Berners-Lee is best known for inventing a markup language, the Hyper Text Markup Language (HTML) that has (of course) become the basis for Web pages. In a very real sense, Berners-Lee invented the World Wide Web! And more. In 2016, Berners-Lee received the prestigious Turing Award for “for inventing the World Wide Web, the first web browser, and the fundamental protocols and algorithms allowing the Web to scale.” Originally a physicist, Berners-Lee received a first-class Bachelor of Arts degree in physics at Queen’s College, Oxford.

Berners-Lee began his career as an engineer for a telecommunications company in England, and later worked as a researcher at CERN in Geneva. While at CERN, Berners-Lee first conceived of the design for hypertext (HTML links), implementing an early prototype known as ENQUIRE. The World Wide Web did not exist yet—but the Internet did, and Berners-Lee then extended his ideas about hypertext to the Internet, in effect inventing the World Wide Web, in his now famous proposal written in 1989. He then designed and developed the world’s first Web browser, WorldWideWeb (no spaces, and later renamed to Nexus to avoid confusion). He then published the world’s first web site, “info.cern.ch.” Naturally, the web site provided an explanation to neophytes (basically, everyone else!) of what a Web page is, and how the Web was intended to link together, or “work.” It also provided how-to information on how to use the web browser to set up a server, and how to build a website. Not bad. Berners-Lee later became Director of the World Wide Web Consortium (W3C), gathering together businesses to help create standards and recommendations for the growing Web. Berners-Lee also conceived of a follow-up “next generation” web, known as the Semantic Web, which would add computer-readable logical statements to web pages to enable computers to understand their contents better. The Semantic Web is a visionary project that perhaps has stalled as the Web evolved into what we now know, but the ideas seem ripe for exploration. In short, Tim Berners-Lee—TBL—is a true pioneer of the World Wide Web, and a hugely influential computer scientist.

Tim Berners-Lee was knighted by Queen Elizabeth II in 2004. In 2007 he was appointed by the Queen to the Order of Merit, an honor limited to twenty four living people. He was elected a Fellow of the Royal Society in 2001. He has been conferred honorary degrees from the likes of Harvard and Yale, as well as Manchester in England, and others. Time Magazine named him one of the 100 Most Important People of the 20th Century in 1999.

France

New York University

Silver Professor of the Curant Institute of Mathematical Sciences

Artifical Intelligence, Deep Learning Networks

LeCun is one of the most important people in the subfield of computer science known as machine learning. In particular, he is one of the original scientists working on Deep Learning systems, which are enormously popular in work on Artificial Intelligence today. LeCun received his engineering degree from ESIEE in Paris in 1983, and his Ph.D. from Université Pierre et Marie Curie in 1987.

LeCun’s long career has been laser-focused on research on neural networks, actually an old technique in machine learning dating back almost to the inception field of Artificial Intelligence—an important subfield of computer science focused on making intelligent applications—in the 1950s. However, LeCun’s research has been mostly on what are now called “Deep Learning” networks, neural networks that are organized in hierarchies of layers, making them more powerful for many tasks like recognizing objects in photos. Not surprisingly, LeCun’s work on Deep Learning attracted the attention of Web giant Facebook, where he now holds the position of Vice President, Chief AI Scientist at the company. He retains the title of Silver Professor of the Curant Institute of Mathematical Sciences at New York University.

LeCun has significant influence at Facebook and NYU discussing and working on improving Deep Learning systems in AI. As Deep Learning has come to dominate many areas of research in AI, in particular for Web companies like Google, Facebook, Amazon, and others, LeCun’s star has rapidly risen in the last decade. LeCun is a member of the US National Academy of Engineering, and recipient of other awards including the prestigious Turing Award in 2019, which he shares with colleagues Geoffrey Hinton and Yoshua Bengio.

Computer Programming, Analysis of Algorithms

Knuth is professor emeritus of computer science at Stanford University. He received his Ph.D. in Mathematics at the California Institute of Technology (Cal Tech). As an undergraduate at the Case Institute of Technology (now Case Western Reserve University), Knuth received the extraordinary honor of receiving his bachelor of science degree together with a master of science in mathematics based on the strength of his work at Case. He also helped redesign an early IBM computer while at Case, and made fundamental contributions to programming—writing a program to help predict the scores of basketball players on his college team.

While an associate professor at Caltech, Knuth wrote the influential The Art of Computer Programming, a tome of seven volumes that quickly became a go-to book for anyone interested in the how’s and why’s of computer programming. Knuth’s publication is a notoriously deep-dive into programming. In fact, Microsoft Chairman Bill Gates once quipped that “If you think you’re a really good programmer ... You should definitely send me a résumé if you can read the whole thing.” His name has become synonymous with the fundamentals of computer programming. Knuth is also the author of Surreal Numbers, a book exploring alternate systems of numbers, as well as numerous articles and contributions to recreational mathematics. He spearheaded the idea of “literate programming,” inviting programmers to think of programming as works of literature, or writing. Winner of many awards, Knuth was inducted into the National Academy of Sciences in 1975. He is one of the true pioneers in that most central of areas of computer science, the art (and science) of writing programs.

Artifical Intelligence, Deep Learning

Hinton has been called one of the “Godfathers of Artificial Intelligence” by media sources for his work on a neural network system known as “Deep Learning.” He divides his year between working for Google Brain, the influential AI group at Google, and as a professor of computer science at the University of Toronto in Canada.

Hinton, along with researchers David Rumelhart and Ronald Wilson, designed one of the key features in modern neural networks, a type of machine learning algorithm that learns from experience. In 1986, he published a description of using backpropagation to train neural networks on data, and this technique has become a lynchpin for all neural network successes to date. Hinton truly is one of the “godfathers” of AI, an honorific especially relevant today as major Web companies like Google, Facebook, Twitter and many others now use neural networks ubiquitously. At Google and the University of Toronto, Hinton focuses on Deep Learning systems, a type of neural networks that involves stacking multiple networks together to create powerful results, like learning to recognize faces and other objects in online photos. Self-driving cars also use Deep Learning systems for autonomous navigation.

Hinton was elected a Fellow of the Royal Society in 1998. With Yann LeCun and Yoshua Bengio, Hinton received the top prize in computer science, the Turing Award in 2018.

Superintelligence was particularly well-received, honored as a New York Times bestseller list and promoted by top minds such as Bill Gates and Elon Musk.

Ranked as among the top thinkers in the world, Bostrom has warned of the dangers of superintelligence, which he feels could become an extreme threat within a remarkably short time after development. In his view, a superintelligence could use agent-like behavior to infiltrate existing systems and do so without arousing suspicions.

Bostrom and other major thinkers in the field contributed to a letter with 23 principles of AI safety. These guidelines continue to provide guardrails for the development of artificial intelligence.

Computer Science Theory, Models of Computation

Lenore Blum (retired) is a professor of computer science at Carnegie Mellon. Blum initially studied architecture, but graduated with a degree in mathematics by taking math classes at MIT, though her bachelor’s was granted by Simmons College, a private women’s college. Blum went to MIT and completed her Ph.D. there in 1968.

Blum began her career at The University of California at Berkeley, though at the time (in the 1960s) they did not provide opportunities for women professors. She then taught at Mills College, where she received a first from Mills: an endowed professorship as the Letts-Villard Chair at Mills. Her success at Mills led her to Carnegie Mellon University, where she became a Distinguished Career Professor of Computer Science at CMU in 1999.

Blum has been active in encouraging women to pursue studies and careers in computer science. In 1971 she helped found the Association for Women in Mathematics. As an activist for women in computer science, Blum has taken the position that low enrollment of women in computer science departments is partially the result of a lack of outreach and support networks that help women find a footing in male-dominated fields like computer science (this has changed much in recent years, though her insights are still quite relevant). Rather than focus on formal barriers like admissions, Blum focused on building support systems for women interested in pursuing careers in computer science. Blum experienced the lack of assistance in her own career both formally and culturally, in the former case by finding she was not permitted to follow her Ph.D. advisor to Princeton University while pursuing her dissertation work, as at the time Princeton did not accept female graduate students. She has done much to pave the way for female computer science students.

Blum’s work in CS focused on theoretical aspects of computer science, notably work in number theory and models of computation inspired by Turing’s original formalism, the Turing Machine. She is the recipient of numerous awards and distinctions, including the Presidential Award for Excellence in Science, Mathematics, and Engineering Mentoring awarded by President George W. Bush. In 2012, Blum became a fellow of the American Mathematical Society.

Computer Security

Schneier’s name is synonymous with computer security. He is also respected as a cryptographer, and writes on issues of personal privacy arising from society’s ever changing relationship with new technology. In 1984, Schneier earned his bachelor’s degree in physics from the University of Rochester in New York. He received a master’s degree in computer science from American University in Washington, D.C. in 1988 and an honorary Ph.D. from the University of Westminster, London in 2011.

Over the years, Schneier has written extensively on core issues and problems with computer security, both for private individuals and for company and government security. Importantly, he has been an outspoken critic—or at the very least, he has sounded caution—of blockchain technology, arguing that it can create more problems than it solves. Central to much of Schneier’s thinking about computer security, he points out that supposedly “bullet proof” technology solutions for establishing security and trust tend to have weak points at the “ends” where humans add and receive data. The human components to end-to-end security is a key theme in his ideas. “Schneier’s Law” was coined by Internet theorist Cory Doctorow in a 2004 speech, capturing this theme: “Any person can invent a security system so clever that he or she can’t imagine a way of breaking it.”

Schneier’s books on computer security issues are written for general audiences, and have been widely read. Notable: Secrets and Lies: Digital Security in a Networked World in 2000; Beyond Fear: Thinking Sensibly About Security in an Uncertain World in 2003; Liars and Outliers: Enabling the Trust that Society Needs to Thrive in 2012, and most recently Data and Goliath: The Hidden Battles to Collect Your Data and Control Your World in 2015.

Computational Complexity Theory

Khot is Julius Silver Professor of Computer Science in the Courant Institute of Mathematical Sciences at New York University. Khot received his bachelor’s degree in computer science from the Indian Institute of Technology Bombay. He received his Ph.D. from Princeton University in 2003.

Khot has made key contributions to computational complexity theory applied to games theory, notably his “unique games conjecture,” in 2002, where he postulated that certain games, known as unique games, are very difficult to solve (for computer science students, they are NP-Hard). Khot’s work on unique games has proven practically relevant, as it helps illuminate certain problems with, for instance, voting results. It has application to what are known as “approximation results” in a variety of fields in disciplines seeking mathematical description and rigor.

Khot received the MacArthur Fellowship in 2016. He was elected a Fellow of the Royal Society in 2017.

Paul and Marlene Borman Professor of Applied Mathematics

Computational Cryptography

Shamir is a cryptographer and professor of computer science at the Wiezmann Institute of Science in Israel. He received a bachelor’s degree in Mathematics from Tel Aviv University in 1973, and a master’s and Ph.D. in computer science at Weizmann in the 1975 and 1977.

Shamir became famous for his co-invention of one of the world’s first public key cryptosytems, RSA (which bears his name: it’s an acronym for Rivest-Shamir-Adleman). The RSA public key system has been widely adopted by businesses and individuals to securely send encrypted messages, as in email or other data transmissions over a network. He has also done pioneering work in visual cryptography, and developed a powerful technique known as “differential” cryptography—though it was later revealed that the top secret National Security Agency (NSA) had developed and used the technique secretly. Nonetheless, for his many important discoveries in the field, Shamir is one of the true fathers of computational cryptography.

Shamir has received many awards recognizing his contributions to computer science and cryptology. In 2002 he received the highest honor in computer science, the Turing Award. He has also been honored by the Vatican with the PIUS XI Gold Medal, and was elected in 2018 as a Foreign Member of the Royal Society for his substantial contribution to human knowledge. Quite a career, indeed.
