NDSU researchers included in rankings of world’s top cited scientists


NDSU researchers are among the top scientists in the world based upon a list compiled by Stanford University.

Originally published in 2019, the rankings are based upon a researcher’s citations for both a single year (2019) and cumulative across their careers. Titled “Updated science-wide author databases of standardized citation indicators,” the list uses algorithms that quantify and systematically rank individuals into consistent scientific fields.

Ranked within the careerlong citation impact list are these NDSU researchers:

• Abraham A. Ungar, General Mathematics

• Alan R. Denton, Fluids and Plasmas

• Dale A. Redmer (Emeritus), Dairy and Animal Science

• Dean C. Webster, Polymers

• Dennis E. Tallman (Emeritus), Energy

• Erik K. Hobbie, Chemical Physics

• Ghodrat Karami, Mechanical Engineering and Transports

• Gordon P. Bierwagen (Emeritus), Polymers

• Guodong Liu, Analytical Chemistry

• Jagdish Singh, Pharmacology and Pharmacy

• Jeremy Straub, Optoelectronics and Photonics

• Kalidas Shetty, Biotechnology

• Kalpana S. Katti, Materials

• Lawrence P. Reynolds, Dairy and Animal Science

• Marinus L. Otte, Environmental Sciences

• Michael D. Robinson, Social Psychology

• Michael R. Kessler, Polymers

• Mukund P. Sibi, Organic Chemistry

• Qifeng Zhang, Nanoscience and Nanotechnology

• Scott A. Wood, Geochemistry and Geophysics

• Stuart G. Croll (Emeritus), Polymers

• Sumathy Krishnan, Energy

• Sylvio May, Chemical Physics

• William W. Beatty, Experimental Psychology

Ranked within the 2019 citation impact list are:

• Amrita Banerjee, Pharmacology and Pharmacy

• Clay Routledge, Social Psychology

• Jiajia Rao, Food Science

• Khang Hoang, Applied Physics

• Kristine J. Steffen, Surgery

• Ned A. Dochtermann, Behavioral Science and Comparative Psychology

• Senay Simsek, Food Science

• Simone A. Ludwig, Artificial Intelligence & Image Processing

The Stanford list is compiled from a set of metrics including total citations; the Hirsch h-index (that quantifies the cumulative impact of a scholar’s work); the co-authorship-adjusted Schreiber hm-index; the number of citations to papers as a single author; the number of citations to papers as single or first author; and the number of citations to papers as single, first or last author. Using data from abstract and citation database Scopus, the values of the metrics are then used to calculate a composite score for the most-cited researchers.

The scores are provided both with and without self-citations to lessen the impact of researchers employing extreme self-citations or the use of citation farms (small clusters of researchers massively citing each other’s work). Institutional affiliation and the respective country are inferred based on most recent publications according to the Scopus data. Besides the composite score, the list also ranks scientists by most common scientific field and two most common scientific subfields of their publications along with the percentage for each based on the standard Science-Metrix journal classification system. The classifications include 22 main fields and 176 subfields.

The updated study was published in PLOS Biology in October.
