She made her debut performing in the Metropolitan Opera on 23 December 2009 as understudy for Kathleen Kim in the role of Olympia in the opera Tales of Hoffman. She had less than four hours notice that she would sing that night, and the curtain was even briefly held past 20:00 to allow her to walk the stage. She interpolated a High A-flat (A♭6) into Olympia's aria, which, at the time, was conjectured to be the highest note to have ever been sung on the stage of the Met.
