Yilin Wang is a staff scientist in the Catalysis Science Group within the Physical Sciences Division at Pacific Northwest National Laboratory (PNNL). She also belongs to the Institute for Integrated Catalysis (IIC) at PNNL. Wang’s research interests are in the areas of applied catalysis, particularly heterogeneous catalyst development, screening, and characterization. After graduating in chemical engineering from Tianjin University in 1994, she worked for two years as an assistant engineer at Yanshan Petrochemical Co., in Beijing, China. She then returned to Tianjin University in 1996 and finished her master’s degree in chemical engineering in 1999. In 2001, she joined professor Wilfred T. Tysoe’s group at the University of Wisconsin-Milwaukee studying surface science and received her doctoral in physical chemistry in 2006. She then pursued postdoctoral research at Texas A&M University under the mentorship of professor D. Wayne Goodman, and at Washington State University with professor Yong Wang, respectively, from 2008-2011. Wang joined PNNL in 2013 as a research scientist. Her research at PNNL includes emission control catalysis, biomass conversion catalysis, and energy storage and transportation. Wang also works on Lab Assist system construction and laboratory safety management.
