In computer science, a “good” h-index is generally 20–30 for mid-career researchers or 40+ for senior leaders; the top 1 % of CS scientists have h-index ≈ 167
What is a good h-index?
A reasonable h-index depends on academic rank and field: assistant professors 2–5, associate professors 6–10, full professors 12–24, and Nobel-level researchers ≥ 35
These aren’t hard rules—just median values from big bibliometric studies. Actual numbers vary wildly by field and sub-field. Compare yourself to peers in your exact discipline, not some universal benchmark. Hirsch’s original paper called an h-index of 40 “outstanding” after two decades and 60 “exceptional.”
What is a good h-index for computer science?
For computer-science faculty, aim for 12–18 to reach associate professor, 25–35 for full professor, and 50+ if you aspire to leadership or institute directorships
Computer science sits near the middle of the h-index spectrum. The top 1 % of all scientists have h ≈ 167, while the top 1 % of computer scientists cluster around 90–110. Elsevier’s 2020 dataset shows median CS h-indices of 14 (assistant), 32 (associate), and 58 (full).
Is 40 a high h-index?
Yes—40 is outstanding for a computer scientist; only the top 2–3 % of CS researchers exceed it
Hirsch’s rule of thumb calls 40 “outstanding” after two decades. Large-scale CS rankings back this up: fewer than 1 in 50 CS faculty worldwide reach h = 40. Guide2Research’s 2026 list shows the 100th-ranked CS scientist at h = 57, so 40 puts you in the top 0.5 %.
What is a good h-index after 5 years?
After five years, an h-index of 3–5 is typical for assistant professors; 8–12 is competitive for early tenure; 15–20 is rare and signals exceptional promise
These figures assume steady publishing in respected venues and active citation accrual. Delays in peer review or niche topics can drag numbers down. Check your h-index annually via Google Scholar or Scopus to catch trends early.
Who has the best h-index?
As of 2026, the highest known h-index belongs to Sigmund Freud at ≈ 280, followed by a cohort of ≈ 3 200 researchers across disciplines with h ≥ 100
Global rankings are discipline-specific. In computer science, the highest h-index is ≈ 190 (2026 update). Remember: h-index doesn’t capture influence outside citation networks—many Nobel laureates in physics have h ≈ 60–80 despite extraordinary impact.
Who is the best computer scientist in the world?
As of 2026, consensus lists place Barbara Liskov, Vinton Cerf, and Tim Berners-Lee at the top based on foundational contributions, awards, and citation impact
- Barbara Liskov – Turing Award (2008) for programming-language design.
- Vinton Cerf – Co-inventor of TCP/IP, Turing Award (2004).
- Tim Berners-Lee – Inventor of the World Wide Web, Turing Award (2016).
These rankings combine h-index (≥ 120 each), awards, patents, and industry adoption. They can shift as new breakthroughs emerge.
Can h-index go down?
No—the h-index never decreases; it either stays the same or rises as new citations accrue
Because the metric is the largest h where h papers have ≥ h citations, any new citation to an existing paper can’t drop the value. The index only stays flat if new papers receive few citations.
What is a good number of citations?
A paper with 10+ citations sits in the top 24 % worldwide; 100+ citations places it in the top 1.8 %
Field norms vary wildly. Experimental biology papers often exceed 200 citations, while theory papers in niche areas may top out at 20–30. Aim for at least 50 citations if you want grant reviewers to notice your work. Web of Science provides percentile benchmarks by subject.
How do you get a high h-index?
Build a high h-index by publishing regularly in top-tier journals, collaborating with established teams, and ensuring open-access availability so more readers can cite your work
- Publish in 2–3 high-impact venues per year that are indexed in Scopus or Web of Science.
- Join large, well-cited consortia—each co-authored paper can add 5–15 citations to every author.
- Archive preprints and final versions in institutional repositories or arXiv to boost discoverability.
- Monitor your profile on Google Scholar and request corrections for name variants.
What is the weakness of the h-index?
The h-index ignores rarely cited outputs (e.g., meeting abstracts) and inflates reviews that accumulate citations without reflecting novel contributions
It also favors long careers over hot new topics—an early-career breakthrough may have high impact but low h-index until citations accumulate. Combine h-index with altmetrics and expert review for a fuller picture.
What is a good number of citations for a professor?
Successful full professors typically have at least one paper with > 1 000 citations and a career total > 5 000 citations
Field medians differ sharply. Computer science professors average 600 citations overall, while biology professors often exceed 2 000. Use Scopus to compare your citation profile against peers in your exact sub-discipline.
Who has the highest h-index in India?
As of 2026, chemist Chintamani Nagesa Ramachandra Rao (CNR Rao) remains India’s sole researcher with an h-index of 100, reflecting a career spanning seven decades and 1 600+ papers
Rao’s record has stood since 2011. No other Indian scholar has matched it despite rapid growth in Indian research output. Track updates on Google Scholar Citations.
Is an h-index of 10 good?
An h-index of 10 is solid for an assistant professor or early-career researcher, placing you above roughly half of peers in most engineering and social-science fields
It means you have 10 papers each cited at least 10 times. The median h-index for assistant professors in computer science is 7–9, so 10 marks you as productive and visible. Use it as a springboard for tenure applications, not as a ceiling.
What is the difference between h-index and impact factor?
The h-index measures an individual researcher’s cumulative impact, while the Journal Impact Factor (JIF) measures the average citations of recent articles in a single journal over two years
Comparing a person’s h-index to a journal’s JIF is like comparing apples to oranges—they answer different questions. Use JIF when choosing where to submit, and h-index when evaluating a scholar’s body of work.
What does h-index mean?
The h-index is the largest number h such that an author has published h papers that have each been cited at least h times
For example, if you have 20 papers with at least 20 citations each, your h-index is 20. Jorge Hirsch proposed this metric in 2005 to balance quantity and impact in a single number. It’s now the de-facto standard for academic evaluation.
