Nine researchers at the Department of Energy's Pacific Northwest National Laboratory are leading the way in solving the world's biggest challenges, as evidenced by other researchers referencing their papers.

These citations are tracked by Clarivate Analytics (formerly part of Thomson Reuters), which analyzed publication and citation statistics between 2005-2015. Clarivate Analytics annually releases a list of scientists from around the world whose citations rank in the top one percent within 21 subject areas. It features the most frequently cited researchers as determined by the extent to which their papers have supported, influenced, inspired and challenged other researchers around the globe.

Energy Storage

Four of the PNNL scientists were recognized in the categories of chemistry and material sciences for their publications and citations on energy storage or battery research.

  • Jun Liu serves as director of the Department of Energy's Battery500 Consortium, a collaboration among national laboratories, academia and industry to develop smaller, lighter and less expensive electric vehicle batteries. Liu is a Battelle fellow who has more than 55 U.S. patents and 400 peer-reviewed publications. Liu has appeared on the list since 2014.
  • Yuyan Shao is an electrochemist and materials scientist focused on electrochemical energy storage and conversion for both transportation and stationary applications. He has more than 100 publications and 40 patents and patent applications. Shao has appeared on the list twice.
  • Jie Xiao is a chief scientist who also holds a joint appointment at the University of Arkansas. Xiao leads research into practical applications and fundamental study of energy storage materials and systems, from micro-batteries for acoustic fish tags to advanced battery technologies for vehicle electrification and stationary applications. She has more than 100 published peer-reviewed journal papers as well as 18 energy storage patents and patent applications.
  • Ji-Guang (Jason) Zhang is a PNNL laboratory fellow focused on development of energy storage devices, including lithium-ion batteries; thin-film, solid-state batteries; lithium-sulfur batteries; lithium-air batteries; and electrochemical devices. He holds 23 patents, with another 17 pending, and has published more than 250 journal papers. Zhang was recognized this year in both the materials science and engineering fields, and he has appeared on the list twice.

Atmospheric Science

Two PNNL scientists were recognized in the geosciences category for their ongoing work to better understand the impact of clouds and small particles in the atmosphere on climate.

  • Steven Ghan is a climate scientist whose work involves a combination of development, evaluation and application of parameterizations for climate models. He works with other team members to understand the atmospheric processes that drive regional and global Earth systems, with a primary focus on climate, aerosol and cloud physics. Ghan has more than 175 publications cited more than 11,000 times.
  • Philip Rasch serves as the chief scientist for climate science at PNNL and is internationally known for his work in general circulation, atmospheric chemistry and climate modeling. He is particularly interested in the role of aerosols and clouds in the atmosphere and has worked on the processes that describe these components of the atmosphere, the computational details that are needed to describe them in computer models and on their impact on climate.

Biology and Health

Two PNNL scientists were recognized for important contributions in pharmacology & toxicology and chemistry that have important implications for human health.

  • Yuehe Lin, a Washington State University professor who holds a joint appointment at PNNL as a laboratory fellow, is a leader in the fields of nanoscience and nanotechnology, electrochemistry, chemical sensors and biosensors. The technologies he's developing can detect important molecules in biological systems, explosives and pesticides and could deliver drugs to fight diseases like cancer. Lin was recognized in the chemistry category.
  • Justin Teeguarden is a chief scientist for exposure science at PNNL who also holds a joint appointment at Oregon State University. He has more than 75 peer-reviewed publications, has co-authored National Academy of Sciences reports and serves on the Environmental Protection Agency's Board of Scientific Counselors Homeland Security Subcommittee.

The ninth PNNL scientist honored is plant physiologist Nate McDowell. He is an expert on the planet's trees and studies the many factors that collectively determine tree health and vulnerability.

The nine PNNL scientists join more than 3,300 researchers on the highly cited researcher list whose work is cited at a level markedly higher than average for their fields.
