Best Chemistry Universities in New Zealand 2026

Each institution's position in the ranking is determined by the sum of the D-indexes (Discipline H-index) of all affiliated scholars whose primary publication area is Chemistry. Importantly, the D-index is a discipline-specific metric; it encompasses only those publications and citations that pertain directly to Chemistry, thus ensuring an authentic and focused measure of impact within the field.

Scope of Research and Selection Criteria

The ranking is derived from the systematic analysis of 279,971 scientist profiles identified across diverse bibliometric databases. Specifically for Chemistry, 279,971 scientists were thoroughly examined. To maintain the quality and relevance of the evaluation, a qualifying D-index threshold of 40 was established for each scientist. Only those with a majority of significant publications in Chemistry were considered. In addition, the scientist’s awards and achievements in Chemistry were taken into account as influential factors.

The threshold for recognizing top researchers within the discipline is set to increase in increments of 10, carefully calibrated in relation to the total number of scholars within each specific discipline, while ensuring that the top 1% of leading scholars are always incorporated into the ranking. An additional requirement stipulates that the proximity between a given scientist’s general H-index and their D-index must not exceed 30%, reinforcing the credibility of discipline-specific research contributions. Awards and other notable achievements continue to act as important qualifiers, further attesting to a scientist's standing in the global Chemistry community.

Verification and Quality Assurance

Recognizing that no raw bibliometric data can fully account for the breadth and depth of scientific accomplishment, the Research.com team has implemented rigorous verification practices. Each scientist profile was manually verified and cross-referenced against an extensive range of reputable publication sources. This careful process was instituted to minimize potential errors or omissions and to further uphold the integrity of the ranking.

Although the number of papers published in high-impact journals and major conference proceedings does not directly influence a researcher’s position in the Research.com ranking, it remains a valuable secondary signal, highlighting a scholar’s substantial and credible contributions within Chemistry.

The ranking positions are established using H-index data sourced from OpenAlex and CrossRef – the most established bibliometric databases accessible to the research community. These sources provide comprehensive and up-to-date citation and publication records. For more detailed information on the procedures and metrics employed, please visit our methodology page.
