Countries citing papers authored by Gregory Ammar
This map shows the geographic impact of Gregory Ammar's research. It shows the number of citations coming from papers published by authors working in each country. You can also color the map by specialization and compare the number of citations received by Gregory Ammar with the expected number of citations based on a country's size and research output (numbers larger than one mean the country cites Gregory Ammar more than expected).
Fields of papers citing papers by Gregory Ammar
This network shows the impact of papers produced by Gregory Ammar. Nodes represent research fields, and links connect fields that are likely to share authors. Colored nodes show fields that tend to cite the papers produced by Gregory Ammar. The network helps show where Gregory Ammar may publish in the future.

Rankless uses publication and citation data sourced from OpenAlex, an open and comprehensive bibliographic database. While OpenAlex provides broad and valuable coverage of the global research landscape, it—like all bibliographic datasets—has inherent limitations. These include incomplete records, variations in author disambiguation, differences in journal indexing, and delays in data updates. As a result, some metrics and network relationships displayed in Rankless may not fully capture the entirety of a scholar's output or impact.
