Which doctor leaves Grey's Anatomy after season 10 to work in Switzerland?

Cristina Yang leaves Grey's Anatomy after season 10 to work in Switzerland.

Cristina’s departure is the culmination of her long-running ambition to become an elite cardiothoracic surgeon and medical researcher. After the season 10 finale, Preston Burke offers her his position at a research hospital in Zurich, Switzerland. Cristina accepts, transfers her hospital shares to Alex Karev, and prepares to leave Seattle.

Her exit is not a death or a temporary transfer. Cristina says goodbye to Meredith Grey, Owen Hunt, Derek Shepherd, and her other colleagues before leaving for Zurich. Surgical resident Shane Ross goes with her to continue training under her. Cristina later remains part of the Grey’s Anatomy world through references and text messages, but Sandra Oh no longer appears as a regular cast member.

A common mix-up is confusing Cristina’s move with Meredith’s career or with Burke’s earlier departure. Cristina is the doctor who relocates to Switzerland, where she takes over Burke’s research-hospital role.
