Miss Posner, 23, graduated with a first in classics from Cambridge, where she was also president of the Jewish society.
She spend the coming year as a “special student” affiliated to Harvard’s Centre for Middle Eastern Studies, where she hopes to perfect her Hebrew and study Arabic.
Once she finishes at Harvard, she will take up a fellowship at Yale where she will study for a masters in global studies. Both, she hopes, will help her develop a career in international diplomacy.
Miss Posner, from Woodford Green, is the first in her family to go to university. She said she was: “very proud to have received scholarships to study at these prestigious universities”.
