hi man, you are not alone in this way. I applied to their PhD program in pure math but not hear any news from them, whereas the graduate director of Dep told me in 11feb that they are reviewing profiles and will announce their decisions up to late feb.
I don't understand what happen there, But I am dieing of being anxious too. would you share me your resume and GPA with me. I have 3.7 Ms. GPA with really strong recommendations and several passed advance graduate courses.
