PNNL

Dr. Honghong “Crystal” Shi is a catalysis scientist at the Institute for Integrated Catalysis (IIC) at Pacific Northwest National Laboratory (PNNL). Prior to joining PNNL, she earned her Ph.D. in Chemical Engineering with honors from the University of Kansas. Shi received her M.S. in Chemical Engineering from the University of Calgary and her B.S. from the China University of Petroleum. Shi's research focus is performing hypothesis-driven investigations into the design of advanced metal and metal oxide catalysts with tailored structures, alongside elucidating the complex surface chemistry relevant to key processes in energy science. The core emphasis of her work lies in catalyst design, spectroscopy, and reaction engineering strategies aimed at uncovering reaction mechanisms in heterogeneous processes.
