Creativity, insight, and application are the hallmarks of Dr. Xin Sun’s applied mechanics and computational materials research at Pacific Northwest National Laboratory. Her advances in lightweight and high-strength materials (including steels) and modeling are vital to energy efficiency and renewable energy and have led to notable weight savings in the U.S. automotive industry. Xin is developing simulation and modeling capabilities for solid oxide fuel cells. Her modeling of physics properties are included as part of the solid oxide fuel cell multiphysics modeling code, or SOFC-MP, a commercial software tool, developed at PNNL, used by fuel cell developers. She also uses the continuum damage mechanics model, developed under DOE-funded programs, to understand fracture mechanisms behind transparent armor for the U.S. Army—work that may enable more resilient battlefield vehicles. A prolific contributor to the scientific community, Xin is on the ISRN Mechanical Engineering editorial board and serves as an associate editor on the ASME Journal of Offshore Mechanics and Arctic Engineering and American Welding Society Welding Journal. She also mentors staff and interns at PNNL and Washington State University, where she is a mechanical and materials engineering professor.

Building accurate, intricate computer models that allow scientists and stakeholders to understand the interplay between Earth, water, clouds, and atmosphere is what Dr. Ruby Leung does at Pacific Northwest National Laboratory. She conducts cutting-edge research and refines models that are vital to predicting climate and understanding the impact of energy policies, new technologies, and our changing climate. As an example, to better simulate climate change effects on hydrologic conditions over mountain watersheds, she developed a unique framework for modeling the regional coupled atmosphere and terrestrial systems. She also applies regional climate models to study hydroclimate processes and climate extremes, and the aerosol effects on regional climate and hydrological cycle. She received her M.S. and Ph.D. in atmospheric science from Texas A&M University. She earned a bachelor's degree in physics and statistics from Chinese University of Hong Kong, where she was the only woman in her graduating class of the physics department.
