Top researchers in the USA on the Top 2% Scientists list 2026
Live Directory analytics: Bandura, Albert (Stanford University, global rank 4) leads the United States single-year 2026 top_researchers panel among 73,459 listed USA scholars, ahead of Ajzen (rank 7) and McClements (rank 11).
Who are the top researchers in the USA on the Top 2% Scientists list?
Direct answer: In ABS Nexora’s United States top_researchers panel (single-year 2026), the national list opens with Bandura, Albert of Stanford University (Psychology & Cognitive Sciences; global rank 4; 12,694 citations), then Ajzen, Icek (University of Massachusetts Amherst; rank 7) and McClements, David Julian (University of Massachusetts Amherst; rank 11). These are Directory ranks (rank_all) for the single-year listing, not a popularity poll and not a Nobel-style prize ranking.
The USA cohort is 73,459 listed scholars — the largest national list, about 29.7% of the single-year country-analytics total (247,376). Average citations in the USA snapshot are about 1,227. For the country-level story see the USA directory hub.
Top 15 USA researchers (single-year 2026)

Every name links to /scholar/{slug}?year=2026&listing=single_year. Example: Ioannidis, John P.A. at Stanford University School of Medicine (rank 23; Clinical Medicine) — useful if you are searching “Ioannidis list USA.”
What fields do the leading US names come from?
The highest-ranked USA names are not a Clinical Medicine sweep, even though Clinical Medicine is the country’s largest field (28,396 scholars — USA field strengths). The top of rank_all in this pull is heavy on Psychology & Cognitive Sciences (Bandura, Ajzen, Gross, Diener), Mathematics & Statistics (Breiman, Tibshirani), Physics (Perdew), and agriculture / food science (McClements, Lal).
Citation volume is a different sort. Gogotsi, Yury G. (Drexel; rank 25) has 33,098 citations in this snapshot; Perdew, John has 30,491; Murray, Christopher J.L. (University of Washington; rank 36) has 42,417. High citations ≠ best composite rank.
Single-year leaders vs career leaders
The career USA listing is a different ranking. Career USA lists 90,855 scholars (~37.29% of that listing’s global country-analytics total). The career top_researchers panel starts with Willett, Walter Churchill (Harvard T.H. Chan School of Public Health; career rank 4; 425,616 citations), then Kessler, Ronald C. (career rank 6) and McEwen, Bruce S. (career rank 8).
| Listing | USA scholars | Example #1 | Global rank |
|---|---|---|---|
| Single-year 2026 | 73,459 | Bandura, Albert | 4 |
| Career 2026 | 90,855 | Willett, Walter Churchill | 4 |
Bandura is #1 in the USA single-year panel and still appears on the career panel (career rank 14). Always state which listing you are citing. The how-to is here: find, verify, and cite a USA Top 2% scientist.

How to read “most cited American scientists 2026”
- Global rank (
rank_all) is the Directory’s default sort for this table. - Citations (all) is
total_citations_allin the same payload — useful, not identical to rank. - Profiles also expose ranks and citations with self-citations excluded (the Directory
nsfields) — see USA self-cited scientists. - A certificate is an overlay on the same profile:
/certificate/{slug}.
