Chang-Jun LiuView profile
Adjunct Professor
Chang-Jun Liu is a Senior Scientist in the Plant Science Group of the Biology Department at Brookhaven National Laboratory, where he has conducted research on plant phenylpropanoid biosynthesis and lignin metabolism since joining in 2005. He also holds an Adjunct Professor position in the Biochemistry & Cell Biology Department at Stony Brook University and serves as Associate Editor for Plant Cell & Environment (2024-present) and Frontiers in Plant Sciences (2015-present). Dr. Liu's educational background includes: Ph.D. in Plant Biochemistry and Molecular Biology from the Shanghai Institute of Plant Physiology, Chinese Academy of Science (1999) Dr. Liu's research integrates approaches from biochemistry, molecular genetics, biophysics, protein engineering, metabolic engineering, and synthetic biology to investigate phenylpropanoid and lignin biosynthesis in plants. His laboratory addresses fundamental questions about how lignin and related compounds are synthesized and incorporated into cell walls, how regulatory networks govern metabolic activity, and how lignification influences cell wall structure and function. A central aim of his research is optimizing plant feedstocks for efficient lignocellulosic biomass utilization. Analysis of Dr. Liu's publication record reveals a consistent trajectory from fundamental biochemical mechanisms to applied bioenergy solutions. His recent work focuses on cytochrome b5 diversity, electron transfer mechanisms in phenolic biosynthesis, and metabolic engineering approaches to modify lignin composition. This research spans from evolutionary studies of lignin biosynthesis across plant lineages to practical applications in bioenergy crop improvement. Dr. Liu has received recognition for his contributions to science, including: Brookhaven National Laboratory Science and Technology Award (2018) Dr. Liu serves as Editorial Board Member for the Journal of Biological Chemistry (2020-present), PNAS Nexus (2024-present), and Plant Physiology Journal (2025-). He is Scientific Lead at the Joint BioEnergy Institute, Feedstocks Division, Lawrence Berkeley National Laboratory, and Project Lead at the Center for Bioenergy Innovation, Oak Ridge National Laboratory. His research is funded by the U.S. Department of Energy through multiple Bioenergy Research Centers. Dr. Liu leads a research group at Brookhaven National Laboratory focused on elucidating the posttranslational regulation and macromolecular organization of lignin biosynthesis, with applications toward developing designer lignins and reducing biomass recalcitrance for sustainable biofuel production. His work addresses the critical challenge of lignin's dual nature: while it impedes enzymatic access to polysaccharides in biofuel production, it also represents the most abundant renewable source of aromatic carbon for high-value bioproducts.
