Priscilla Chan’s story begins with a family decision made during one of the most turbulent periods in Vietnam’s history. Her grandparents sent their teenage children away by boat in search of safety during the Vietnam War, uncertain whether they would ever see them again.

Years later, Chan would become the first person in her family to attend university, graduate from Harvard, train as a paediatrician and help build one of the world’s most prominent philanthropic organisations focused on science and healthcare.
Alongside her husband, Mark Zuckerberg, Chan has helped steer the Chan Zuckerberg Initiative (CZI) towards research into human biology, disease, education and technology. Her career in medicine, particularly her experience treating children with rare conditions, has played a major role in shaping that focus.

Priscilla Chan’s parents fled Vietnam by boatAs per a TOI report, Chan was born in Massachusetts to Chinese-Vietnamese refugee parents. Her family’s journey to the US began during the Vietnam War, when her grandparents made the difficult decision to send their children away by boat.

Chan has spoken about how her parents were teenagers when they left Vietnam. According to her accounts, the family faced the possibility that they might never be reunited. It reportedly took around a decade before the family was together again.

Her parents eventually arrived in the US as refugees with little money and limited English. They worked to establish a new life and create better opportunities for their children.
Chan has recalled that she began helping her family navigate language barriers when she was just six years old, translating for them. As a teenager, she also worked at the front desk of the restaurant her parents eventually managed.Her childhood experiences of financial uncertainty and feeling different from those around her later influenced the way she spoke about education, opportunity and access.She became the first in her family to attend collegeChan went on to become the first person in her family to attend college, enrolling at Harvard University.

She studied biology and graduated in 2007. During her time at Harvard, she received financial aid and became involved with the Phillips Brooks House Association, a public service programme.

Chan has credited the organisation with providing support during her university years and helping strengthen her interest in service.

After Harvard, she briefly worked as an elementary school science teacher before moving into medicine.

From teacher to paediatricianChan attended the University of California, San Francisco (UCSF), where she earned her medical degree and trained as a paediatrician.

She subsequently worked at UCSF and San Francisco General Hospital for eight years, caring for children and their families.

Her experience with patients suffering from rare diseases became particularly influential. Chan has described meeting families who had spent months or even years searching for an explanation for their children’s illnesses.

In some cases, doctors simply did not have the answers.

Those experiences exposed Chan to the limits of existing medical knowledge and strengthened her belief that advances in basic science could eventually lead to better diagnoses, treatments and cures.

Priscilla Chan and Mark Zuckerberg launched CZIIn 2015, Chan and Zuckerberg established the Chan Zuckerberg Initiative, a philanthropic organisation initially focused on advancing human potential and promoting equality.

In their founding letter, the couple said they planned to devote 99% of their Facebook shares during their lifetimes to philanthropic purposes connected to those goals.

CZI went on to develop programmes spanning science, education, and justice and opportunity, with Chan playing a central role as co-founder and co-CEO.

Her medical background has been particularly important to the organisation’s work in science and healthcare.

Chan Zuckerberg Initiative pledged billions for scienceScientific research became one of CZI’s major areas of philanthropy.

In 2016, Chan and Zuckerberg announced plans to commit $3 billion over 10 years towards efforts to help scientists prevent, cure or manage diseases.

One of the initiative’s early major commitments was $600 million for the Chan Zuckerberg Biohub, designed to bring scientists and engineers together to develop new tools and technologies for biomedical research.

The $3 billion figure represented the couple’s broader philanthropic commitment through CZI rather than a personal donation from Chan alone.

What does the Chan Zuckerberg Initiative fund?CZI has supported research across several areas, including infectious diseases, cell biology, neuroscience and biomedical imaging.

The organisation has also invested in biological datasets, research infrastructure and tools intended to help scientists better understand human biology and disease.

One of its major scientific projects is the Human Cell Atlas, an international effort to create detailed maps of the cells that make up the human body.

CZI has also increasingly explored the use of artificial intelligence in biology. The organisation says advanced computational tools and large biological datasets could help researchers analyse complex biological information and speed up scientific discovery.

Why Priscilla Chan focuses on science and healthcareChan’s approach to philanthropy is closely connected to her experience as a doctor.

Treating children with rare diseases showed her how frustrating it can be for families when medicine does not yet have an explanation for a child’s condition.

Those experiences helped shape her belief that improving scientific understanding is essential to developing better medical treatments.

Through CZI, that philosophy has translated into funding for research tools, biological datasets and projects aimed at understanding how cells work and how diseases develop.
