Shan Elected to American Academy of Arts and Sciences

Shu-ou Shan, Caltech's Altair Professor of Chemistry, has been elected as a member of the American Academy of Arts and Sciences, one of the nation's oldest honorary societies. She joins 251 other new members this year who have distinguished themselves in academia, the arts, industry, journalism, philanthropy, policy, research, and science.

"We celebrate the achievement of each new member and the collective breadth and depth of their excellence—this is a fitting commemoration of the nation's 250th anniversary," said the Academy's president, Laurie L. Patton, in a press release. "The founding of the nation and the Academy are rooted in the inextricable links between a vibrant democracy, the free pursuit of knowledge, and the expansion of the public good."

Shan's research primarily focuses on protein biogenesis, tracing the complex molecular pathways that ultimately lead to the production of proteins in the body. It is a long and twisting road from the instructions provided by a genetic code to the creation of new proteins and the manifestation of biological effects. Much can happen along the way. Shan's research has delved into the various selection and triage mechanisms—these can be thought of as proofreaders and filters—that intervene to ensure that proteins are properly assembled and delivered to their correct locations.

Shan's lab then uses these pathways as models to try to understand how accuracy and complexity can be generated in biological settings from noisy signals and inanimate biomolecules.

Shan earned her undergraduate degree at the University of Maryland and completed her graduate work at Stanford University. After a postdoctoral position at UC San Francisco, she joined the Caltech faculty in 2005 and was named a full professor in 2011. Shan became the Altair Professor in 2019 and served as Caltech's executive officer for biochemistry and molecular biophysics from 2015 until 2025.

Among the numerous honors and awards Shan has received are the American Chemical Society's Nobel Laureate Signature Award for Graduate Education in Chemistry, the Mildred Cohn Young Investigator Award from the American Society of Biochemistry and Molecular Biology, and the National Academy of Science Award in Molecular Biology. She is also a member of the National Academy of Sciences.

Founded in 1780 by John Adams, John Hancock, and 60 others, the American Academy of Arts and Sciences aims to serve the nation by cultivating "every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people." Academy members work with other experts to produce "reflective, independent, and pragmatic studies that inform public policy and advance the public good." Fellows and foreign honorary members have included George Washington, Benjamin Franklin, Duke Ellington, and Albert Einstein.

New fellows and foreign honorary members will be inducted into the academy during a ceremony in Cambridge, Massachusetts, in October 2026. More information about the newest members of the American Academy of Arts and Sciences can be found on the Academy's website.
