A researcher’s publications in a given field and the number of citations are factors that were taken into account when compiling the 4th edition of the prestigious international Research.com ranking. Researchers from our Institute were recognized in two of the twenty fields included in the ranking: Prof. Ryszard Amarowicz in chemistry and Prof. Andrzej Ciereszko in biology and biochemistry.

The ranking of Research.com is based on the D-index (discipline-specific H-index), which takes into account a researcher’s publication output in a given field and the number of citations. The data comes from OpenAlex and CrossRef. According to the creators of the ranking, their goal is to inspire scientists, companies, and politicians from around the world to explore the research conducted by leading experts and to provide the entire scientific community with the opportunity to discover who the leading experts are in specific fields of research, in different countries, and even within individual research institutions.
