So who exactly is the woman who has captured the Facebook billionaire’s heart?
Here are five things to know about Priscilla Chan:
1. She’s a high achiever
Chan, who was born in Braintree, Mass., was valedictorian of her class when she graduated from Quincy High School in 2003. She then went to Harvard where she majored in biology.
According to her Facebook page, from 2007-2008, Chan taught science to middle school kids, a job she describes as “hanging out with the little ones and trying to explain how the world works.” But she didn’t stop there: On May 14, the same day as Zuckerberg’s 28th birthday, Chan graduated from UCSF medical school with a focus on pediatrics.
