At PNNL, scientists, engineers, programmers, and researchers work together to apply advanced theories, methods, algorithms, models, evaluation tools and testbeds, and computational-based solutions to address complex scientific challenges affecting energy, biological sciences, the environment, and national security.

Shippert Contributes to First-ever Observations of Methane’s Impact on Greenhouse Effect

In recently released work published in Nature Geoscience, researchers led by LBNL drew on a decade’s worth of detailed atmospheric measurements to present the first observational outcome from methane’s influence of the greenhouse effect at the Earth’s surface. Tim Shippert, an engineer with PNNL’s Data Integration team, contributed to the analyses that measured methane’s impact.


Award-winning CCSI Toolset Gets Open-Source Release on GitHub

The Carbon Capture Simulation Initiative recently released its CCSI Toolset, a computational tools and models suite, as open-source software now available on GitHub. Designed to maximize learning and reduce risk during the scale-up process for carbon capture technologies, the CCSI Toolset features contributions from PNNL scientists involving computational fluid dynamics models used to simulate the complex physical and chemical processes of carbon capture.


Scholtz Recognized with SIGCHI Academy Award

Congratulations to Jean Scholtz, chief scientist of PNNL’s Visual Analytics group, who received the CHI Academy Award from the Association for Computing Machinery’s Special Interest Group on Computer–Human Interaction, known as SIGCHI. The award is presented annually to principal leaders of the field whose efforts have shaped the disciplines and innovation of human-computer interaction.


Rallo Named to Panel Examining Life Science-Technology Connections

In March, Robert Rallo, ACMD Division Data Sciences Group Lead, will serve as a panelist for a session devoted to “Technology Partnerships: The Engine Driving Innovation in Life Sciences” as part of the Life Science Innovation Northwest conference in Seattle. The panel will examine how life sciences research, especially the data resulting from it, will require even more engagement with technology companies to affect progress.


Encouraging Global Innovation

This spring, Sotiris Xantheas, will join the Tokyo Institute of Technology as a visiting professor with the World Research Hub Initiative, known as WRHI. Xantheas, a PNNL Laboratory Fellow, is among the inaugural class appointed under the initiative that brings leading international researchers to Japan for scientific collaboration. He is aligned to WRHI’s Materials and Devices hub and will focus on chemistry research.
