Impact Scholars

Carver College of Medicine Impact Scholars are selected based on the Hirsch index, also known as the H-index, which represents the number of research papers a faculty member has published, and the papers’ impact as determined by how many times they have been cited by other scientists and scholars in subsequent research articles.

For example, a researcher with an H-index of 50 has published at least 50 articles that each have been cited at least 50 times. An H-index increases as multiple papers are cited multiple times. The H-index calculations for the Carver College of Medicine Impact Scholars are based on research abstract and citation data from Scopus. Carver College of Medicine Impact Scholars are faculty who have achieved H-index scores of 100 or higher (“gold” level) and 50 or higher (“silver” level).
