Bibliometric Analyses of Hot Research Topics and Collaborative Patterns among ASMS Members in 2020
Magnus Palmblad (Leiden University Medical Center) and Nees Jan van Eck (Leiden University)
In 2020, we revisited and updated the collaborative network of the current and recent members of ASMS using bibliometric methods. Our analysis shows that in May 2020, 4,643 current and former members are connected in a single, large, co-authorship network, including many of the most prolific authors in the field. As in previous analyses, the network shows clear topographical differences between small, PI-driven academic groups and “big science” laboratories. The co-authors with the strongest links have long worked together at the same location.
Looking at research fields, we see hot topics from molecular and cellular biology, clinical mass spectrometry as well as ion mobility, mass spectrometry imaging and computational methods. Fundamental studies in chemistry and instrumentation represent more mature topics among ASMS members, with a more stable number of new publications per year.
The methodology and data acquired at that time were described in a 2018 JASMS article. Both the co-authorship and research topics map below are provided with a number of information overlays, such as scientific seniority, countries and average publication year.
