James E. Geach D-index placement in Physics in 2026 - data summary

  • The chart plots the discipline H-index (D-index) of all 3,678 Physics scientists ranked by Research.com in 2026, grouped into 59 ranges running from 70–71 to 185+ D-Index.
  • James E. Geach, a Physics scholar from University of Hertfordshire, records 84 D-Index - the 28th percentile of the discipline.
  • 28% of ranked Physics scientists score the same or lower than James E. Geach, and about 72% score higher.
  • The median of the discipline falls in the 96–97 D-Index range, and James E. Geach ranks below the median.
  • The most crowded range is 80–81 D-Index, holding 167 scientists (5% of the field).
  • 55% of the field sits in the lowest quarter of the value range (up to 98–99 D-Index), so the distribution is heavily right-skewed and high scores are rare.
