Countries citing papers authored by J. Roger Downie
This map shows the geographic impact of J. Roger Downie'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 J. Roger Downie with the expected number of citations based on a country's size and research output (numbers larger than one mean the country cites J. Roger Downie more than expected).
Fields of papers citing papers by J. Roger Downie
This network shows the impact of papers produced by J. Roger Downie. 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 J. Roger Downie. The network helps show where J. Roger Downie may publish in the future.
Co-authorship network of co-authors of J. Roger Downie
This figure shows the co-authorship network connecting the top 25 collaborators of J. Roger Downie. A scholar is included among the top collaborators of J.

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.
