She was born in Busan, South Korea,[2] the daughter of a Korean mother and a Polish father.[3][4][5] The family eventually moved to Englewood, New Jersey, where she grew up[6] and graduated from Dwight-Englewood School.[7] About her childhood, she stated that "it's almost embarrassing how well-behaved I was, which is probably why I do things like spit water on myself on stage as an adult".[8] She attended Oberlin College before transferring to New York University's Tisch School of the Arts.
