The Highly Cited Research resource captured the people behind the most influential publications in 21 broad subject categories in life sciences, medicine, physical sciences, engineering and social sciences based on citation metrics.

Within their category, these individuals represent less than one-half of one percent of all publishing researchers—truly an extraordinary accomplishment. This highly cited research was identified by the Thomson Reuters team between 2000 and 2008 based on analysis of papers covered in Web of Science from 1981-2008.
