You can also color the map by specialization and compare the number of citations received by Michael Häder with the expected number of citations based on a country's size and research output (numbers larger than one mean the country cites Michael Häder more than expected).
This network shows the impact of papers produced by Michael Häder. 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 Michael Häder. The network helps show where Michael Häder 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.
