Shu-ou Shan

Shu-ou Shan is a Chinese American biologist who is a professor at the California Institute of Technology. Her research combines mechanistic enzymology with biophysical characterization techniques (e.g. Cryo em and fluorescence spectroscopy) to understand biogenesis pathways. She was awarded the 2024 National Academy of Sciences Award in Molecular Biology.

Early life and education Shan was born and raised in Shanghai. She moved to the United States after high school, and studied chemistry at the University of Maryland, College Park. She was a doctoral researcher at Stanford University, where she worked alongside Daniel Herschlag on RNA catalysis. She was first introduced to mechanistic enzymology there. She moved to University of California, San Francisco as a postdoctoral researcher, where she worked with Peter Walter on cell biology. Co-translational describes processes that occur at the same time as translation during protein synthesis. Using an array of biophysical characterization techniques, Shan looks to build a model that can predict what happens to nascent proteins as they emerge from the ribosome and their environment impacts these processes.

Shan studies molecular chaperones (proteins that assist in the folding or unfolding process) and how they protect proteins from mis-folding, sometimes even repairing mis-folding or aggregation. 2007 Arnold and Mabel Beckman Fellow 2011 Protein Society Irving Sigal Young Investigator Award 2013 American Chemical Society Nobel Laureate Signature Award for Graduate Education in Chemistry 2013 American Society for Biochemistry and Molecular Biology Young Investigator Award 2020 Caltech Altair Professor of Chemistry 2024 National Academy of Sciences Award in Molecular Biology
