  10. 10 R. Maiolino United Kingdom · #3,222 worldwide overall 69.0 of 174 papers here in the top 10%

Ranked on their work in Instrumentation alone: how many more of their papers here reached the world top 10% for their subfield and year than the 10% expected, among 218,955 ranked researchers with a paper here. Each paper counts once, so many strong papers outrank one famous one, and a long record of ordinary papers does not climb. Identities come from OpenAlex author disambiguation, which occasionally merges or splits people.

Where is the best place to study Instrumentation?

Among universities, judged by research, Harvard University, California Institute of Technology and Princeton University score highest, combining standing in the field's ranking, citation excellence, specialisation, size, growth and international reach. Research strength is one signal when choosing where to study; it does not measure teaching.

Universities only. The score blends standing (50%), citation excellence (20%), size (15%), specialisation (5%), growth (5%), international reach (5%), 2022-now; growth compares 2018-21 with 2022-25 and counts up to +20%, since a jump from a small base is mostly noise. Standing is the score in this field's institution ranking, three quarters over all time and a quarter 2022-now; excellence averages the two windows too. Four years alone undercount fields such as AI, where many conference and arXiv papers from 2022 on carry no affiliation in the data.

Is Instrumentation research growing?

Output in 2022-2025 was 2% higher than in 2018-2021, peaking in 2025. The fastest-growing topics are Advanced Optical Sensing Technologies.

Its share of all research

Growing output can still be a shrinking share: all of science grows. This is Instrumentation as a percentage of every work published that year, 0.052% in 2024.
