Runze Mao

Dr. Runze Mao's scientific journey began at Peking University under Prof. Xin-Shan Ye. His work led to photo-induced glycosylation methods later applied to automated glycan assembly. After earning master's degree with honors in 2016, he joined Prof. Xile Hu's group at EPFL, Switzerland. There, he innovated green catalytic transformations from feedstocks to value-added compounds. In September 2020, he obtained his PhD in chemistry with honors. Dr. Mao then honed his expertise in directed evolution and biocatalysis as a postdoctoral researcher under Prof. Frances H. Arnold (2018 Nobel Prize laureate in Chemistry) at Caltech, USA. He expanded the catalytic repertoire of metalloenzymes, addressing pressing challenges at the interface of biological and synthetic chemistry. Dr. Mao has published papers in top journals, including Nat. Catal. (2), Nat. Chem. (1), Nat. Synth. (2), JACS (3), and Angew. Chem. (2), and his academic excellence has been recognized with many awards, including the Reaxys Global PhD Prize finalist, and the Chinese Government Award for Outstanding Self-Financed Students Abroad.

From August 2024, Dr. Mao assumed the role of Assistant Professor at Tsinghua iBHE, bringing his diverse expertise to bear on new scientific frontiers.

Enzymes can catalyze the most challenging transformations, such as nitrogen fixation and methane oxidation, under exceptionally mild conditions. However, fully harnessing their potential for synthetic applications is still in the infancy. Dr. Runze Mao's lab is focused on developing innovative biocatalytic strategies by integrating chemistry, biology, and artificial intelligence to address major challenges in synthesis, catalysis, and biomolecular engineering. By combining interdisciplinary approaches from synthetic chemistry, synthetic biology, computational chemistry, and computational biology, we aim to redesign and expand nature's biosynthetic machinery to explore uncharted chemical spaces. These efforts will deepen our understanding of fundamental enzymology and reaction mechanisms, thereby advancing synthetic biology and facilitating the rapid assembly of molecules with biomedical and materials significance. Dr. Runze Mao has published 22 high-impact academic papers in enzyme catalysis and synthesis, including 11 papers as the first author in prestigious international journals, including Nat. Catal. (2 papers), Nat. Chem. (1 paper), Nat. Synth. (2 papers), J. Am. Chem. Soc. (3 papers), Angew. Chem. Int. Ed. (2 papers), and Chem. Sci. (1 paper).
