An annual list of highly cited researchers named 17 PNNL scientists for their influential and oft-referenced work. Put out by Clarivate Analytics, the list recognizes the performance of exceptional researchers whose papers ranked in the top 1 percent by citations in their field.

At their heart, citations represent connections between researchers working to benefit far more than the scientific community.

“These researchers create gains for society, innovation, and knowledge that make the world healthier, richer, more sustainable, and more secure,” said David Pendlebury, senior citation analyst at the Institute for Scientific Information at Clarivate Analytic’s Web of Science Group.

Their scientific achievement advances understanding in the following PNNL mission areas.
