Best English medium universities and schools (Istanbul)

Dear Istanbulites, I was wondering if anyone had any ideas on the above? I am currently a lecturer of Political Science in the USA (Montana) but thinking of moving to Istanbul, my daughter's father is from there, and I am interested in the best English speaking medium school for my daughter as well as private English speaking universities where I might be able to continue to lecture. Thank you for your thoughts and ideas on the above and kind regards. Sally Anne Corcoran
