On May 5, 2026, Research.com released the 5th edition of the annual ranking of the best scientists in the field of chemistry. The comprehensive report was created to offer the academic community and the general public a transparent look into the contributions of leading chemistry researchers.

This report serves as a vital resource for academic institutions, policymakers, and aspiring scientists globally. By highlighting the most prolific contributors, the analysis allows stakeholders to identify shifts in academic excellence and regional research hubs.

For the 2026 edition, analysts meticulously examined over 18,200 scientist profiles across OpenAlex, CrossRef, and other bibliometric databases. The rigorous evaluation process ensures that only the most impactful scholars are featured in the final ranking.

To guarantee the highest standards of academic excellence, the ranking requires a minimum D-index of 40 for inclusion. Beyond the D-index score, the evaluation also considers the proportion of work contributed to the specific field and the recognition of notable awards.

The key findings for the 5th edition of the best chemistry scientists ranking

• Scientists from the United States dominate the ranking with 363 scholars in the top 1,000, solidifying the nation's leading position in global chemistry research.
• China showed the most improvement year-over-year, increasing its representation to secure the second spot with 191 leading scientists.
• Michael Grätzel from the École Polytechnique Fédérale de Lausanne in Switzerland holds the #1 global rank with an outstanding D-index of 296.
• The Chinese Academy of Sciences is the most heavily represented institution, boasting 32 leading scientists within the top 1,000.
• For the top 1% of scientists in the ranking, the average D-index is an impressive 229.7, indicating a massive concentration of high-impact citations among the elite.
• European nations remain highly competitive, with Germany and the United Kingdom featuring 77 and 52 leading scholars, respectively.

Latest studies in chemistry research

Recent studies in chemistry highlight groundbreaking advancements in sustainable energy and alternative materials. Researchers have developed a new form of aluminum known as cyclotrialumane, which features a unique triangular structure that can outperform costly rare metals in complex chemical reactions. By offering an alternative that is nearly 20,000 times less expensive than precious metals such as platinum, this discovery paves the way for cleaner, more affordable industrial processes.

Another major focus in the current academic landscape involves utilizing environmental elements to power the growing Internet of Things (IoT). Scientists recently created a dirt-powered fuel cell that leverages naturally occurring soil microbes to generate electricity for underground agricultural sensors. Operating flawlessly in both dry and flooded conditions, the device produced 68 times the power required by its sensors, offering a robust alternative to toxic batteries.

Despite these technological leaps, the scientific community continues to grapple with the practical challenges of scaling these discoveries. Ensuring that engineered microbial systems and novel aluminum compounds transition safely from the laboratory to global industries requires robust testing and continuous international collaboration.

Countries with the highest number of leading chemistry scientists

The United States continues to host the highest number of top-tier chemistry researchers globally, maintaining its premier status with 363 scholars in the top 1,000. Despite this dominant position, the data reflect a subtle year-over-year shift as other geographic regions rapidly expand their scientific footprint.

China has demonstrated the most significant growth compared to the previous year's report, expanding its featured cohort to 191 leading scientists. This rapid surge underscores the nation's aggressive investment in advanced research initiatives and its growing influence over the global chemistry landscape.

European nations maintain a robust presence in the upper echelons of chemical research, led by Germany with 77 featured scholars. The United Kingdom follows closely with 52 scientists, while Japan remains the most prominent Asian hub outside of China with 50 representatives.

Please note that the country associated with a scientist is based on the affiliated research institution according to MAG, not on their actual nationality.

Institutions with the highest number of leading scientists

The Chinese Academy of Sciences has secured the top institutional ranking this year, boasting an impressive 32 leading chemistry scientists. This represents a notable upward trajectory from the previous edition, mirroring the broader national trend of increasing bibliometric dominance in the discipline.

The University of California, Berkeley closely follows as the leading American institution, housing 22 top-ranking scholars in its chemistry department. Other top-tier American universities, including Northwestern University and Stanford University, also maintain strong showings but face intense competition from rising international hubs.

Tsinghua University has firmly established itself in the third overall position with 17 top researchers, further solidifying the shifting geographic concentration of academic talent. Meanwhile, Germany’s Max Planck Society leads the European institutional rankings, securing the fourth spot globally with 15 highly cited scientists.

Advancing chemistry research through online universities

The integration of digital platforms into graduate education has profoundly expanded the reach and impact of modern chemistry research. As academic institutions adapt to evolving educational paradigms, online universities have become essential for equipping aspiring chemists with advanced analytical skills without geographic constraints.

According to a 2025 report by the National Council for State Authorization Reciprocity Agreements (NC-SARA), exclusively distance education enrollment reached over 1.6 million students in the fall of 2024. This broader academic trend is heavily influencing the sciences, as online universities now offer rigorous virtual laboratories and computational modeling courses necessary for cutting-edge chemical synthesis.

H-index ranking—leaders, averages, and distribution

Europe holds the highest-ranking chemistry scientist globally, with Michael Grätzel from the École Polytechnique Fédérale de Lausanne in Switzerland securing the #1 spot with a D-index of 296.

North America is led by George M. Whitesides of Harvard University in the United States, who holds the #2 global rank with a D-index of 271.

Asia's leading researcher is Yadong Li from Tsinghua University in China, ranking #5 globally with a D-index of 224.

Oceania is represented at the top by Shi-Zhang Qiao of the University of Adelaide in Australia, who ranks #16 globally with a D-index of 200.

Africa's premier chemistry scholar is Mika Sillanpää from the University of Johannesburg in South Africa, securing the #201 global spot with a D-index of 138.

Finally, South America's foremost researcher is Elson Longo from the Federal University of São Carlos in Brazil, ranking #545 globally with a D-index of 115.

The average D-index for the top 1% of scientists is 229.7, compared to an overall average of 124.71 across the entire ranking.

Top-tier scholars also dominate research output, with the top 1% averaging 1,361.2 publications compared to the overall average of 677.33.

The gap is most pronounced in citations, where the top 1% average 234,216.7 citations against an overall ranking average of 64,660.84.
