On March 21, 2023, Research.com published the 9th edition of the annual best computer scientist ranking. The report aims to increase the online visibility of established and upcoming scholars in the field of computer science.
Additionally, researchers, academics, businesses, and other decision-makers in an organization can refer to our report as their source for experts in a particular research topic in computer science. Since we also include the scientists’ country and professional and academic affiliations, searching and networking with the right experts become even more convenient.
For the 2023 report, our research team reviewed over 14,400 scientist profiles using various bibliometric sources. Led by our chief data scientist, Imed Bouchrika, PhD, the Research.com team analyzed several indicators and metrics to determine each scientist’s inclusion in the ranking.
The threshold for the D-index (Discipline H-index) was set at 30 for most computer science publications. Moreover, the inclusion criteria are based on the discipline D-index, the proportion of contributions within the given discipline, as well as awards and achievements of the scientists.
The field of computer science has had an abundance of significant breakthroughs and advancements in recent years. These include improvements in quantum computing, machine learning, artificial intelligence, natural language processing, edge computing, blockchain technology, and cybersecurity. The discoveries and progress in these areas have found their practical application in crucial sectors such as healthcare, finance, education, and transportation.
In healthcare, for instance, providers are embracing AI technology in a variety of services—from caring for the elderly to reading X-rays and improving administrative systems. Meanwhile, the previous releases of DALL-E in 2021 and ChatGPT in 2022, both laid the groundwork for many exciting developments in natural language processing and multimodal AI we can expect in the future.
Discoveries in quantum computing, on the other hand, have the potential to revolutionize computing power and solve complex problems faster than traditional computers. IBM, for example, is expected to announce this year a processor that bucks the trend of prevailing quantum bits, or “qubits,” being implemented to date.

WORLD’S BEST COMPUTER SCIENTISTS RANKING
The United States maintains its top position as the country with the most computer scientists: 583. That number though has decreased from last year’s 591. Among the top 1% of scientists, affiliations are quite diverse, with 5 researchers working for United States institutions, 2 scientists from Canadian universities, and one from Germany, the U.K., and Australia.
Meanwhile, China and the United Kingdom also kept their second-place and third-place ranking from the previous year with 92 and 64 scientists, respectively.
The top 10 countries in our report mostly held on to their positions with the exception of Italy, which relinquishes its position to France. The other leading countries are Germany, Canada, Switzerland, Singapore, Israel, and Australia.
Please note that the country associated with a scientist is based on the affiliated research institution according to MAG, not on their actual nationality.
In 2023’s ranking report, the Massachusetts Institute of Technology (MIT) dropped from its previous number-one ranking with 36 scientists. It shares this place with Carnegie Mellon University, also with 36 scientists. Stanford University is this year’s top institution for computer scientists with 38 in total.
While 2022’s report saw only American universities and companies dominating the top 10 institutions, this year, we have a new research university in the ranks. ETH Zurich, a public research university in Zürich, Switzerland enters at number 10.
Among the 20 leading institutions, 16 are U.S.-based universities and companies, two are in Switzerland (ETH Zurich as well as the École Polytechnique Fédérale de Lausanne) the other four are based in Switzerland (ETH Zurich as well as the École Polytechnique Fédérale de Lausanne), one is located in the United Kingdom (University of Oxford), and one is in Israel (Weizmann Institute of Science).
Outside of research universities, private companies Google and Microsoft employ the highest number of best computer scientists that appeared in our report. Twenty-seven and 25, respectively.
Online education has become a safe and viable way for the best universities in the world to deliver courses and online degrees. Online universities are borderless and allow computer science students and scientists to access specialized training courses that may otherwise be difficult to obtain if they are not available locally. Online education also often provides a flexible schedule, so it enables individuals to effectively balance research activities with other commitments, such as teaching, work, or family responsibilities.
As a result, universities have opened their doors to online collaboration, which facilitates information exchange among students, researchers, and professionals. The Princeton Institute for Computational Science & Engineering (PICSciE), for example, conducts online workshops and live training.
Moreover, online universities can offer extensive digital libraries and databases that students and researchers can access. They can also offer research tools like reference management software, statistical analysis tools, and data visualization tools that can further strengthen and support academic and research endeavors.
For North America, Professor Anil K. Jain of Michigan State University leads the list of best computer scientists in our 2023 report with a D-index of 203. Professor Jain’s research focuses on artificial intelligence and machine learning.
For Europe, Professor Francisco Herrera of the University of Granada in Spain ranks ninth in the report with an h-index of 161. His research topics also revolve around AI.
For Oceania, Professor Rajkumar Buyya from the University of Melbourne, Australia placed 11th in the world with a D-index of 156.
Professor Lei Zhang of Hong Kong Polytechnic University occupies the 30th spot in the world ranking and leads other Asian scientists with a D-index of 136.
For the Middle East and Central Asia, Professor Ian F. Akyildiz of the Technology Innovation Institute, United Arab Emirates leads the list of best computer scientists with a D-index of 131. Professor Akyildiz focuses on computer networks.
The average D-index for the top 1% of scientists is 175 against an average of 90 for all 1,000 scientists included in the ranking.
For 2023, the average number of published articles for the top 1% of scholars in the ranking is 1,047 against an average of 473.7 for all the scientists.
The average number of citations for the top 1% of scientists is 203,704.5 against an average of 47,000.68 for all the scholars in the ranking.
