(b Boston, 17 Oct, 1980)
American dancer. She trained at Boston Ballet School (1994–98), and joined the company in 1998, promoted to principal in 2003. She then moved to the Royal Ballet as first soloist and was promoted to principal in 2006. A dancer whose delicate proportions belie her powerful technique and dramatic attack, she dances a wide range of repertory, and has created roles in Alastair Marriott's Tanglewood (2005), Wheeldon's Fire (part of Homage to The Queen, 2006) and Electric Counterpoint (2008), and McGregor's Chroma (2006).
