Congratulations to McGowan Institute for Regenerative Medicine deputy director Stephen Badylak, DVM, PhD, MD, professor in the Department of Surgery at the University of Pittsburgh and director of the Center for Pre-Clinical Tissue Engineering within the McGowan Institute, as his h-index (Scopus) has reached 100.   The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist. The index is based on the set of the scientist’s most cited papers and the number of citations that they have received in other publications.

This is a prestigious accomplishment. A recent study identified that there were only 3,160 researchers world-wide (living and deceased) that had an h-index (Google Scholar) greater than 100.  [Note: There are different services that calculate the h-index. On Scopus, Dr. Badylak’s h-index is 100; on Google Scholar, his h-index is 119.]  The study identified 21 other researchers across the University of Pittsburgh with a h-index that exceeded 100.  Other McGowan Institute for Regenerative Medicine affiliated faculty members who have also achieved this same success include:  Krzysztof Matyjaszewski, PhD; Timothy Billiar, MD; Simon Watkins, PhD; Anthony Demetris, MD; John Kellum, MD; Rocky Tuan, PhD; and Derek Angus, MD.

There are 418 cited publications that Dr. Badylak has authored/co-authored, and those publications have been cited over 46,000 times.  Some of the most cited publications in Dr. Badylak’s bibliography are:
