Sweet Briar College announced that Woo would become the 13th president of the college; and was instated on May 15, 2017, replacing president Phillip C. Stone. Within six months of her arrival, Sweet Briar College underwent a comprehensive restructuring, consisting of an academic reset that replaced general education with a core curriculum on women leadership; tuition reset which brought down the published tuition from $50,000 to $21,000; and a curricular realignment that brought the number of majors from 42 to 16. In the fall following the restructuring, first year enrollment went up 42 percent.
