Brief bio: I got my bachelor’s degree in School of Life Science, Shandong University and doctorate in the group of Prof. Yuzhong Zhang, State Key Laboratory of Microbial Technology, Shandong University. During my Ph.D, I mainly focused on the native supramolecular architecture of photosynthetic membrane in red algae, including single-cell Porphyridium cruentum and multi-cell Polysiphonia urceolata and Porphyra yezoensis, using atomic force microscope (AFM). After I got my Ph.D, I went to UK and worked in University of Liverpool as a research associate in the group of Prof. Luning Liu. Currently, I’m working in State Key Laboratory of Microbial Technology, Shandong University as a postdoctoral fellow under the supervision of Prof. Yuzhong Zhang. With the help of Prof. Liu and Prof. Zhang, I studied the structural variability, coordination and adaptation

of cyanobacterial thylakoid membranes and cryo-EM structure of cryptophyte PSI–LHCI. We applied high-resolution AFM imaging to draw a landscape view of the native arrangement of membrane complexes in the thylakoid membranes from cyanobacteria. Our results provide insight into the heterogeneity, compartmentalization, and functional regulation of the cyanobacterial photosynthetic apparatus, which is extendable to other membrane systems in bacteria, chloroplasts and mitochondria. The naturally occurring organizational features of thylakoid membranes could be important considerations for the future engineering of artificial photosynthetic systems to underpin biofuel production. The unique cryptophyte PSI–LHCI structure provides a framework for delineating the mechanisms of energy transfer and quenching in cryptophyte PSI–LHCI and understanding the evolution of red lineage photosynthesis by secondary endosymbiosis.
