Sixteen UCI faculty members are part of the Highly Cited Researchers list for 2022. Both quantitative and qualitative analyses are used to identify individuals from across the globe who have demonstrated significant and broad influence in their chosen field or fields of research. The preliminary list of Highly Cited Researchers is drawn from the papers that rank in the top 1 percent by citations for field and publication year in the Web of Science citation index over the past decade. The methodology that determines the “who’s who” of influential researchers draws on the data and analyses performed by bibliometric experts and data scientists at Clarivate’s Institute for Scientific Information.

The UCI scientists listed are:

  • Amir AghaKouchak, professor of civil and environmental engineering
  • Steven Allison, professor of ecology and evolutionary biology
  • James Bullock, dean of the School of Physical Sciences and professor of physics & astronomy
  • Steven Davis, professor of Earth system science
