Priscilla Chan

Priscilla T. Chan (born February 24, 1985) is an American pediatrician and philanthropist. She earned a bachelor's degree in biology from Harvard University and a medical degree from the University of California, San Francisco, completing her pediatrics residency there before practicing at San Francisco General Hospital. Chan married Mark Zuckerberg, co-founder of Meta Platforms, in 2012, and the couple has three daughters. In 2015, they established the Chan Zuckerberg Initiative as a limited liability company structured for philanthropic and investment activities, committing 99 percent of their Facebook shares—valued at billions—to support goals including curing all diseases by the end of the century through biomedical advancements, reforming education systems, and promoting community justice. As co-CEO of the initiative, Chan has overseen grants and investments exceeding $5 billion by 2025, prioritizing empirical progress in areas like cellular imaging tools and single-cell analysis for disease research, though the organization's for-profit elements have drawn scrutiny for potential tax advantages over traditional charitable structures.

However, according to an Instagram post by Zuckerberg in 2023, Chan converted to Judaism in 2022.
