In a blog post, Coursera co-founder Daphne Koller announced she is leaving the company to join Alphabet subsidiary Calico.

Koller founded Coursera with Andrew Ng back in 2012 after working together on artificial intelligence research at Stanford. The two supported the company’s growth until Ng left to become chief scientist at Baidu’s research arm.  Today Coursera has grown to teach 20 million students material from 1,300 courses.

Though both have now officially moved on to new challenges, Koller and Ng remain co-chair’s of the Coursera Board of Directors. Rick Levin has been the CEO of Coursera since 2014 when he left his post as President of Yale University.

Calico was created by Google back in 2013 to tackle human aging and diseases associated with age. Koller is already on the Calico website as the company’s new Chief Computing Officer and will be beginning her official duties next week.

“At Calico, I will work on the development of new computational methods for analyzing biological data sets, to help move to achieving these important scientific and societal goals,” said Koller in a blog post.

We reached out to Koller and will be updating this post with additional information. Until then, we wish her the best.
