Columbia medical PhD decision still pending

[Jalish]

Hello all,

I am kinda new here. So I applied at Columbia Medical Center's Integrated PhD program (Fall 15). I was invited to interview on January 16. We were supposed to get the decisions by the forth week after interview. However, I am still waiting for my result.

My interviews went well and I am a recent Columbia master's degree graduate, which kinda made me optimistic about it. But I am really nervous now and didn't get any response from the program coordinator after I had sent an email. Any idea/ suggestion/ shared experience?
